Greetings reading!
This post may be interesting to those who wondered (or only intends to ask) the question of using lubricants when assembling a caliper.
Background to repair B12.
So, when all consumables and spare parts for brake system Profit, work began. And the question of the question is: to stop on the recommendations of Manual to Suzuki Bandit. 1200 and use only Dot4 as a lubricant when installing the piston of the caliper, or apply additional lubricants? Since the memory of the brake failure on the highway was still alive, then there was a desire to progress a little, and the manual should be smeared with something like a manual ... what?
In the field of view, the MS-1600 paste was inevitably from the VMP-car with recommendations to apply it in the following nodes:
"Guide calipers (layer thickness -0.1mm)
Non-working surfaces and ends brake shoes
Piston surface (layer thickness -0.1mm)
Elastomeric Cuffs Calipers (!) »
In general, a very universal pasta. And she was purchased.
A little later, a specialized paste for pistons of ATE calipers 03.9902-0501.2 was bought. german company Athe, producing brake mechanisms For 90 years, it causes confidence). By the way, this paste may be more accessible if it is ordered through it through the BMW catalog - number 83199407854.
These pastes even appear very different. And my interest began to try to figure out which of the properties of these lubricants are appropriate in the piston caliper, and which is not very. And the very first thing that I decided to see is like a Dot4 brake fluid (glycolic base) behaves when contacting these pastes.
Formerly, a small commentary on the experiment.
It is obvious that the medium in which the pistons move in the caliper should be slippery and small. And the brake fluid is such. It has good adhesion and metal and rubber. Moreover, the pistons are better sliding on the cuff due to the fact that the cuffs themselves are innerAs a rule, not smooth, but have roughness (in appearance they are matte) - it contributes to the best retention of the brake fluid on the surface of the cuff. From this you can withdraw the requirement for the paste for brake cylinders: it should not worsen the hold on the surfaces of the cuff and metal of the brake fluid. That is, the brake fluid should have a high adhesion to the paste itself. Well, how can I appreciate adhesion? Just see how a drop of liquid behaves on the surface.
Ate paste is perfectly wetting, therefore, it will not contribute to the ousting of the brake fluid from the friction pairs. It may be wetting even better than pure metal. Well, drops on the paste MS-1600 are like water on the paraffin ...
In addition to low adhesion, the MS-1600 paste to Dot4 can notice a significantly higher viscosity of this paste in comparison with ATE paste. I suppose this property is also important. The less the viscosity of the lubricating medium, the more accurately the braking force is transmitted, and even more informative brakes. Manufacturers of calipers work on the decline in the friction of the pistons about the details of the caliper: anthers and cuffs are made very subtle, and even refuse anthers at all (this reception is used in sports), and here - a viscous medium, besides, capable of outstanding the braking fluid. And in composition, the question is a silicon, mixed with bentonite (clay). The presence of the mineral in the brake circuit of the motorcycle, to put it mildly, as "not conceptually".
So, low adhesion to glycolic DZH, high viscosity, the presence of solid bentonite particles in the paste - all this, in my opinion, does not make this paste MS-1600 optimal for its use as a paste for brake cylinders.
Of course, it can be noted that there is some anti-corrosion protection of the cylinder, but still the properties of this paste are more appropriate in other nodes. And Emeska found their use - the hairpins, ends and the back side of the pads were treated with a very thin layer of this paste. There she is the place.
P.S. Some observations when working with ATE paste: 
1) She swells a little in Dot4, but it does not completely dissolve.
2) when pumping calipers, small surplus Ate paste was removed along with brake fluid - It was noticeable through the transparent brake fluid plum hose.
3) With the lubrication of the anthers, it is useful to pay attention to its groove - distributing the paste before mounting the cylinder, we will further reduce the likelihood of the "subcinition" of the caliper.
All car systems during its operation must be good. But some attention must be paid to the brakes. After all, often the life of the driver, passengers, other participants in the movement and pedestrians depends on the state of the brake system of the machine. Periodically, it needs to be serviced. This is to replace brake pads, disks, liquids, as well as calipers. For example, lubricant for brake cylinders when maintaining and replacing is simply necessary. We will talk about all this.
Lubrication guide caliper
Before moving directly to the cylinder, you need to deal with its guides. During operation, there is a large amount of heat. This leads to the fact that the compound is often accompanied by tightly. This also applies to the guides that begin to twist. There is nothing good in this, as this may lead to serious consequences. Sweeping contributes to the fact that the pads will be constantly pressed to the disk. This leads to significant overheating of the system. As a result, the pads are burning, the discs become curves. Yes, and the tire in such conditions can easily light up. That is why when servicing a caliper, it is necessary to process guides with special lubricant. What exactly, we will understand this article.
Properties of lubricant for cylinders and guides
Since the node refers to the hard-loaded and in the process of work heats up to 300 degrees Celsius, and with aggressive ride and above, the approach must be appropriate. Lubricant for brake cylinders should have the following characteristics:
It is based on the above parameters, a grease for brake cylinders and guides should be seamless. Fortunately, the assortment is just a huge assortment, so there should be no choice with a choice of work.
Copper lubricant for brake cylinders and calipers
It is the most common and popular among motorists. High temperatures are not afraid and is inexpensive, it makes it so popular. Most often used for processing disks, brake pads, as well as for brackets and other brake system elements. It is worth noting what is applied to reverse side Products. If these are pads, then their front side should not be covered with any lubricant, it concerns the disks.
The process of applying paste is also extremely simple. For this, the surface being processed is cleaned from dirt and corrosion. Further, the brush is applied with a tassel and is evenly distributed over the entire surface. It is worth noting that it is sold and in the cans, in this case it needs to be sprayed, after reading the instructions for use.
Basic base for high-temperature lubrication
On the shelves of auto shops are currently just a huge selection. But if you figure it out, then there are only 3 extensive groups:
- mineral base;
- synthetic basis;
- mineral or synthetic basis with a small amount of metals.
If you understand what kind of boot grease should be used brake cylinderThe best suits the one that is made on a synthetic basis. This is due to the fact that it is neutral to rubber and plastic products. Consequently, anthers do not eat and is ideal for processing brake piston or guide caliper. The base used gives a number of advantages, such as low evaporation, high temperature threshold, insoluability in water and other liquids. In general, an excellent choice is true, not always budget.
It is much cheaper than lubricant for pistons of mineral brake cylinders. But it is still better suitable for guides, since it is able to withstand temperatures from -45 to +180 degrees Celsius.
Lubrication with the addition of ceramic particles
About new Developmentwhich has already managed to gain popularity. It is expensive, but the stated benefits are very encouraging. Raising performance characteristics Lubricants are achieved due to the presence of a small fraction in ceramics. At the moment it is one of the best methods for protecting brake cylinders and their landing places from corrosion. In addition, the processed nodes exclude the possibility of sharp temperature drops, the formation of dirt and dust on the surface.
Despite the high cost of such products, it is extremely popular among motorists. It can be used as a lubricant that is less loaded compared to the front. Among the most popular manufacturers high quality Liquid Moli boasts. Well, now we go further and consider some more extremely important points.
How is the maintenance of the brake system?
Often, the complex lubricant is recommended when replacing brake pads or disks. There is nothing difficult here. First inspect the condition of the guides. Clean the fingers I. planting From rust and process a certain amount of lubrication. Copper, graphite, etc., is suitable for piston, then the lubricant is needed to reduce friction and corrosion protection. The surface of the part is desirable to handle in a small amount. ceramic lubricant. It effectively protect the surface from rust.
An extremely important detail is that it is worth regularly checking the state of the anther. If he is torn, no lubricant will help. First you need to replace and then lay the lubricant material. In addition, it should not be too much, as it will begin to squeeze through anthers and cuffs, which is not good.
Many experts recommend not to save on lubricants for calipers and buy only proven products. For example, the optimal lubricant for the pistons of brake cylinders on silicone basis. It is completely safe for anthers and at the same time is high-temperature. Consequently, it works efficiently both in the winter and summer.
Car service specialists often do not fulfill their direct duties. For example, the calipers and guides must be cleaned when replacing the pads, but no one does. Therefore, it is better to do it yourself, especially since there is nothing complicated and even a beginner will cope. You should not neglect the maintenance of the brake system, but also to look there every 500 kilometers of the mileage also does not make sense. Inspect everything during the replacement of brake pads.
What lubricant is better to take?
It is advisable to use different types Lubricants depending on the work being processed. For example, the guide caliper is perfectly suitable for it is inexpensive and withstands high temperatures. Protects metal products from corrosion and prevents stripping. One of the most accessible options is TRW products.
The optimal lubricant for the pistons of brake cylinders should be on silicone or ceramic basis. Best manufacturer In this regard - FEBI. Cheap and angry. But the anti-graded Liqui Moly is not recommended for bookmarking the piston boot, as it can cause the destruction of the rubber seal.
The anti-graded paste is great for processing the brake pad plate and holding a bracket. Usually it ends with it. Remember that the lubricant of the brake cylinder cylinder should not be performed with pasta that corrupt rubber seals. This can lead to the complete destruction of the piston and the caliper.
Let's summarize
As you can see, there is nothing complicated in the maintenance of the car brake system. But at the same time it is extremely important to regularly lubricate all elements of the caliper that each time they work at high temperatures. Pay attention to the dust of the guide fingers. They are also subjected to wear, resulting in a rather unpleasant knock on irregularities. It happens due to the fact that the finger is freely dangling in the seating area and is not held with a plastic sleeve.
As for lubricants, now they are simply a huge amount. Any paste for lubricating brake cylinders, if it is designed for this, suitable for use. It is not recommended to lubricate the parts of the brake system by simple motor Oil or solidol, etc., all this will not lead to anything good.
Many of the brake system details with due service are capable of serving 200-300 thousand kilometers and more, it concerns calipers, guides, pistons, etc. Pads and wheels are more consumable, but it is also advisable to watch them too much. All this will allow you to feel more confident to feel behind the wheel and to know exactly that the brakes will not let it down, because everything is lubricated and checked there. Often, the problem is found precisely with the jamming of the guides and the tight stroke of the brake cylinder, which occurs in 90% of cases due to the insufficient amount of lubrication. If, with each replacement of the pad, lubricant for anthers of brake cylinders will be used, then you will not know the problems with the braking system of the car.
The condition of the vehicle braking system seriously affects the safety of its operation. Therefore, it must be serviced and check regularly. One of the components of this system is brake calipers. It is about them, as well as the guide calipers will be a question today.
We will look at what lubricant for calipers and guides is better to use, and why it is needed at all. Different groups are applied for this. lubricantsWe tried to consider this question as detailed as much as possible.
Varieties of lubricants
Lubricants are usually sold in the form of a spray or pasta. What should be lubricant for calipers? The choice directly depends on the style of the ride of a particular driver. For example, on sports cars Or when working in extreme conditions, the caliper is heated to a temperature of about + 300 ° C. And with normal use, this figure is usually from + 150 ° C to + 200 ° C. Also, do not forget that in winter the caliper is constantly exposed to dirt, moisture and chemical reagents.
Also read our advice on what brake pads are better to use in the car -
Basic lubrication requirements for calipers and guides:
- saving characteristics when contact with brake fluid and water;
- preservation of indicators at low temperatures (-35 ° C ... -50 ° C);
- the absence of aggressive impact on the components of the car from plastic or rubber;
- heat resistance - the tool should be high-temperature and maintain characteristics at temperatures above + 200 ° C.
Many motorists use cheap materials that do not meet the requirements listed. For example, such lubricants include a popular lithol, graphite lubricant, nigrol, and the like. Certain tasks are performed, but not so effectively, as required in this case. Therefore, we recommend buying high-quality developments of well-known manufacturers.
Currently, the market contains the following categories of lubricants for brake calipers:
- high-temperature anti-grade with metals;
- development on the base mineral Oil;
- tools on the base synthetic oil.
Synthetic or mineral lubricants with metals
These high-temperature contamaged facilities for servicing calipers can operate in a large temperature range - from -180 ° C to + 1100 ° C. Consider the fact that the pastes manufacturers always indicate this feature on the packaging or in the application instructions.
The basis of this material is mineral or synthetic oil with the addition of a certain amount of molybdenum or copper particles, as well as thickeners. These lubricants, in turn, are divided into the following categories:
- Comprehensive means with aluminum, copper and graphite content.
- Lubricants in which metal elements are replaced by ceramics and magnesium silicate.
- Copper pastes with graphite adding.
- The means based on the Molybdenum disulfide or copper.
These lubricants include the following products:
- comprehensive tools: Loctite №8060 / 8150/8151, Huskey 2000 Lubricating Paste and Anti-Seize Compound for High Temperature, Wurth Al 1100;
- paste without metallic particles: Textar Cera Tec, Huskey 400 Anti-Seize, Liqui Moly Bremsen-Anti-Quietzch-Paste;
- copper-based paste: Liqui Moly Kupfer-Paste, Marly Cooper Compound, Permatex Copper Anti-Seize Lubricant, Huskey 341 Copper Anti-Seize, Mannol Kupfer-Paste Super-Hafteffekt, Molykote Cu-7439 Plus Paste, Valvoline Cooper Spray;
- molybdenum lubricants: Huskey Moly Paste, Loctite №8012 / 8154/8155.
Mineral Oil Lubricants
Such pastes contain a bentonite that makes them more dense. Also as part of the funds of this category there are fatty acids and metal particles. The main advantage of such lubricants is a stable operation at temperatures from -45 ° C to + 185 ° C. This means that the paste retains its qualities and perfectly copes with the task - the lubrication of the guide calipers.
Tools based on synthetic oil
Such products are commonly used not only to maintain brake calipers, they are suitable for other parts of the brake system. These compositions contain synthetic oil and additives, providing a long service life, protection against corrosion and oxidative processes. There are both thickener. Lubricants based on synthetic oil are not afraid of contact with water, acids, brake fluid. Usually they operate in the temperature range from -40 ° C to + 300 ° C.
Statistics show that many car owners who serve them on their own give preference to copper lubricants for brake calipers and guides. Consider the main features of these compositions.
High temperature copper lubricants
The composition of such products includes three main components:
- fine copper in the form of small particles;
- synthetic and mineral oil;
- anticorrosive additives.
These funds are sold in the form of a spray or pasta. Due to high viscosity, they fall into all the gaps and do not wash out from there. Copper lubricants work in an impressive temperature range, do not evaporate and minimize the effects of friction forces.
But it is necessary to apply copper lubricant:
- Parently prepare the work surface of the element, clearing it.
- Carefully apply the substance to the surface, preventing dirt from entering.
- Do not delete an extra part from the parts.
Caution! If aluminum calipers are installed on your car, it is prohibited to use copper lubricants, as it will lead to aluminum contact corrosion
Overview of popular lubricants for brake calipers and guides
MS-1600. it domestic developmentwhich refers to the segment of high-temperature versatile funds. Pasta can operate at temperatures from -50 ° C to + 1000 ° C. The lubricant is resistant to the negative impact of moisture, reagents, alkalis, etc. It also does not damage the rubber components of the automotive brake system. Developers recommend lubricating with this means end and non-working surface brake pads, as well as guides and pistons of calipers.
MS-1600 does not react with brake fluids such as DOT 3, DOT 4, DOT 5.1. The value of the 100-gram MS-1600 tube is approximately $ 6-8. There are also 5 grams in stock stickers, which is enough to process one set of brake pads.
Caution! MS-1600 lubricant is unsuitable for use with DOT 5.0 brake fluid
Molykote Cu-7439 Plus. Means american production, which is based on semi-synthetic oil and copper powder. One of the most common lubricants for calipers, which contributes to the following features:
- low evacuators;
- work in the temperature range from -30 ° C to + 600 ° C;
- solubility resistance and washes.
High-temperature lubricant Molykote CU-7439 Plus prevents the corrosion of the braking system components. This tool is advised to use famous automotive companies, including Nissan, Subaru and Land Rover..
Slipkote 220-R DBC. No less interesting lubricant, which is even allowed to be used in drinking water supply systems. Reviews indicate that it is one of the most suitable options for processing guide calipers. But it is not easy to buy it. In most cases, it is ordered in foreign online stores. SlipKote 220-R DBC can operate at temperatures from -46 ° C to + 299 ° C. The basis of the composition is synthetic oil, as well as additives that endow it with anti-corrosion and protective properties. An essential "minus" of this fund was its price - about $ 20 per 85-gram tube.
Caution! Lubricant SlipKote 220-R DBC is not suitable for use with drum brake mechanisms.
Xado Verylube. This lubricant is characterized by more affordable price. It helps prevent the jams of the pad. The tool is available in the form of a spray in a 320-millilitoneal canister. The tool can operate in the temperature range of -35 ° C ... + 400 ° C. Does not affect negatively on parts of rubber. During use, it is recommended to apply the composition in several layers, while before applying the following it is necessary to wait until each layer is dry. A fairly quality product worth about $ 4.
Caution! Liqui Moly Bremsen-Anti-Quietzch-Paste - Lubrication, which was originally designed for guide calips, but then the manufacturer decided to attribute it to the anti-graded segment. The reason is a large number of negative feedback from users. Developers do not advise using this tool for bookmarking in anthers and lubricants of brake calipers guide.
What lubricant for calipers is better to buy?
The article turned out to be quite voluminous, so it is necessary to make a small summary. During lubrication selection, take into account the following:
- terms of use and style ride;
- car model;
- cost of lubricant;
- brake system design.
If you do not use the machine in extreme conditions, the available development of the MS-1600 type or XADO Very Lube will be fully suitable.
The maintenance of the car brake system includes operations:
- Replacing pads and disks
- Cleaning and lubrication of brake calipers
- Check and replace brake fluid
- Processing adjacent surfaces with non-stick compositions, protection of brake hoses.
Preparations used when servicing brake mechanisms:
- Quick cleaner Schnell Reiniger, article 1900.
- Brake fluid Bremsenflussigkeit Dot4, Article 8834. 8832, 3098, 8836
- Silicone spray Silicon-Spray, Article 3955 (7567).
- Aluminum spray Aluminium-Spray, article 7533 (7560).
- Copper Paste Kupfer-Paste, Article 7579, Copper Aerosol 3970, 3969
- Synthetic lubricant for the brake system, spray Bremsen-Anti-Quietsch-Spray, article 3079, 7573. Pasta - Bremsen-Anti-Quietzch-Paste, Article 7585, 3077.
- Rust solvent with molybdenum MOS2-ROSTLOSER, Article 1986
- anti-slip pasta for Anti-Quietsch-Paste guides, article 7656.
Checking the thickness of the brake pads and the state of the pistons of the calipers is necessary at each maintenance car. The replacement of the pad is necessary in the case when it is obvious that the brake pads of the pads are stronger than the critical, until the next service.
Replacing disks: It is performed with a reduction in the thickness of the working surface of the disc is less permissible (measured by a caliper), during critical bias (see the instruction on the car), the beating is measured by an indicator rack. As well as in the presence of strong corrosion, cracks and other damage. Replacement brake discs It is only produced in pairs, both on one axis of the car with a simultaneous replacement of the brake pads (regardless of their condition).
Checking the state of the brake fluid: produced with each maintenance, but not less often than once a year. Criteria for replacement: Liquid operation (see instruction on a car), a sharp change in the color of the liquid (AM .: Damage and cloud), the boiling point of the liquid less than 165 ° C. Synthetic brake fluids tend to absorb water during operation, which leads to a decrease in the boiling point. The boiling point of the liquid can be measured directly or on the relative indicator - electrical conductivity. The easiest and easiest way is to measure electrical conductivity. The tester has three indicators. If when the electrodes are immersed in the brake fluid, a green indicator is lit, then everything is in order, the brake fluid is fresh. If yellow, then the moisture content is within 1-1.5% and further operation is possible. If the red is burning, then the moisture content of the limit is 3% and should be replaced as quickly as possible.
Pad replacement procedure: With any construct of the caliper, a rust solvent with molybdenum MOS2-ROSTLOSER is required, article 1986 on fastening parts and seats brake pads for easy operation. On the "floating" caliper, unscrew the lower bolt fixing the brake cylinder on the bracket. Throw down the caliper up and fix in this position for the pendant details. For fixing it is convenient to use a wire hook. Remove old pads from guide grooves. Remove the guide to the supports of the caliper from the nest. Clean the landing places of the pad with a metal brush and spray to the remnants of contaminants, a quick cleaner Schnell Reiniger, article 1900. The guide of the caliper and their sockets are cleaned from the old lubricant and completely degrease the quick cleaner. Dry details.
Drown the pistons of brake cylinders (it is convenient to use clamp, if not special tool). When jealous or excessive effort in the movement of the pistons to remove rubber anthers Cylinders, remove pollution and spray the Silicon-Spray Silicone Spray Bender, Article 3955 (7567). "Razing" the piston of the caliper, consistently squeezing it out of the cylinder using the brake pedal and beats the shoebank. Check the ease of movement of the piston and re-spray the silicone spray. Wear a boot back. If it is impossible to restore the operation of the brake cylinder, replace it or repaired with the mandatory polishing (or replacement) of the piston and replacing the brake cuff with a boot.
Assembly: Before installing the brake pads, lubricate their guides (contact with the pads) surface on the caliper with a synthetic lubricant for the brake system, spray Bremsen-Anti-Quietsch-Spray, article 3079. The same lubricant is processed by the rear side of the pads and the surface of the anti-slip plates (if they are Provided with a complete set). Lubricate the guides of the caliper and their anti-slip pasteraths for the anti-Quietsch-paste guides, article 7656. Avoid excessive application.
Set the items to the place, collect a caliper. Before twisting the fastening bolts, it is recommended to lubricate the thread to choose from aluminum spray, copper paste or synthetic lubricant for the brake system. After assembly, it is necessary to clear the disk from the traces of the used compositions and from the conservation lubricant, use the Schnell Reiniger quick cleaner, the article 1900.
The sequence of actions when working with opposite calipers is the same. Difficulties may occur only when the pads are extracted, so it is necessary to use rust solvent with MOS2-ROSTLOSER molybdenum, article 1986. Springs and locking pads are lubricated before installing aluminum spray, copper paste or synthetic lubricant for the brake system.
ATTENTION: When working with cars equipped with ABC system, with caution to handle the ABC sensors and their connectors. Be sure to clean the comb with which the sensor reads the wheel speed signal.
Replacing brake discs: for replacement brake disc The rust solvent with molybdenum MOS2-ROSTLOSER should be sprayed, the article 1986 on the mating disk surfaces and the hub, into the holes for the heel or bolts. Fully remove the caliper, unscrew the drive screws (if any). Sometimes, for example, on Mercedes and SUV Toyota, you have to remove the disk along with the hub and later separate the disk from the hub using the press. Before installing a new disk, clear the mating surfaces with a quick schnell reiniger cleaner, the article 1900, dried and apply the separating lubricant, to choose from: aluminum spray, copper paste or synthetic lubricant for the brake system. The same compositions need to handle fasteners and its adjacent surfaces.
Lubrication for calipers and guides make it easier to operate the operation of the brake system, as they work in difficult conditions. There are several types of lubricants. We will try to systematize information, and answer a number of questions of the auto owners of interest.
Types of lubricants
In particular, we will deal with such themes:
Types of lubricants
Immediately it is necessary to indicate that manufacturers share lubricant into two types - paste and spray. Before moving to the listing of their types and stamps, you need to determine what characteristics must have a caliper lubricant. With an aggressive driving style or riding on mountain serpents, the caliper temperature can reach + 300 ° C, and in urban conditions it can warm up to + 150 ° C ... 200 ° C. In addition, moisture, dirt, reagents that are sprinkled by road are affected by the caliper. Therefore, lubricant for calipers and its guides should be:
- non-aggressive in relation to rubber and plastic parts of the machine;
- do not lose its properties when exposed to water, brake fluid or other substances that can be washed or dissolved;
- , that is, not to lose its temperature properties at + 180 ° C or more;
- should not lose its physical properties with significant frosts (from -35 ° C and below).
Universally used cheap lubricants do not provide the conditions described. We are talking about graphite paste, Litolet, Nigrol and their other analogues. That is, for normal work The brake system, and in particular the caliper, it is necessary to use modern developments.
Currently, manufacturers are produced by the following groups of lubricants for calipers:
First group - mineral or synthetic pastes using metals. They relate to type high-temperature anti-grade. Their working range is very wide, and is approximately -185 ° С ... + 1100 ° С (Each lubricant has its own working range).
The substance is based on synthetic or mineral oil, which adds thickeners, as well as metal particles (copper or molybdenum). These include the following subtypes:
- complex pastes, which include powder copper, aluminum and graphite;
- copper and graphite powder in their composition;
- paste without metal particles, instead of which magnesium silicate and ceramics are used;
- copper-based lubricants or disulfide molybdenum.
Examples concrete marks Lubricants of this type:
- complex pastes - Huskey 2000 Lubricating Paste and Anti-Seize Compound for High Temperature, Loctite No. 8060/8150/8151, Wurth Al 1100;
- copper pastes - HUSKEY 341 Copper Anti-Seize, LIQUI MOLY Kupfer-Paste, Mannol Kupfer-Paste Super-Hafteffekt, Marly Cooper Compound, Molykote Cu-7439 Plus Paste, Motip Koperspray, Permatex Copper Anti-Seize Lubricant, Pingo Kupfer-Paste, Valvoline Cooper SPRAY, WURTH SU 800;
- paste without maintenance of metals - Huskey 400 Anti-Seize, Textar Cera Tec, Liqui Moly Bremsen-Anti-Quietzch-Paste;
- paste with Disulfide Molybdenum - HUSKEY MOLY PASTE, ASSEMBLY LUBRICANT & ANTI-SEIZE COMPOUND, LOCTITE №8012 / 8154/8155.
Pastes belonging to this group can be applied to the heading fingers of brake calipers and any high-loaded friction surfaces, except for the working surfaces of the brake pads!
Second group - Mineral Oil Paste. They include a bentonite acting as a thickener. In addition, metal particles and fatty acids added here. The main advantage of mineral-based lubrication - sustainable work in the temperature range from -45 ° С ... + 180 ° С. That is, the paste does not follow and does not lose its properties. Thus, it is great for lubricating guide calipers by car operated in sparing conditions. An example of lubrication of this type - Teroson VR500.
Third group - synthetic oil based lubricants. This is the most universal compoundsbecause it is suitable not only for lubricating calipers, but also other elements of the car braking system. Lubricants are made of purified synthetic oil, as well as additives having anti-corrosion, antioxidative, anti-wear qualities. Also in the composition of the thickener. Synthetic oil based lubricants possess excellent characteristics . They do not dissolve in water, brake fluid, alkali and acids, do not evaporate, and also have dielectric properties. The operating temperature range is approximately from -40 ° to + 300 ° С.
Examples of lubricants - Molykote as-880n Grease, Permatex Ultra Disk Brake Caliper Lube, Slipkote 220-R Silicone Disc Brake Caliper Grease And Noise Suppressor, Slipkote 927 Disc Brake Caliper Grease.
The area of \u200b\u200btheir use wide. They are used to lubricate bearings and rolling bearings, as well as other parts operating under high temperature and significant pressure.
One of the most popular types of pastes and sprays for calipers and guides are copper lubricants that belong to the type of lubricants using metal. Briefly stay on it.
Copper Lubricant (High Temperature)
She, like other lubricants for calipers, refers to the type of high temperature. That is, capable of withstanding significant temperature overload during the operation of the brake system.
Copper lubricants consist of three main substances - chopped fine copper, oil (mineral and synthetic), as well as some substances that are intended to counter corrosion. Lubricants are implemented in the form of a paste or spray. They have a greater viscosity, so penetrating the gaps, do not flow from there.
Advantages of copper lubricants lies in wide temperature operating range, reducing friction forces, no evaporation and dew points. If you make solutions to use the copper lubricant, you must comply with the conditions for its application. Firstly, working surface Details must be carefully cleaned. Secondly, the lubricant should be applied carefully so that along with her to the item did not get trash. Thirdly, it is not necessary to remove excess lubricant.
If the caliper of your car is made of aluminum, it is impossible to use copper lubrication, because contact corrosion of aluminum will occur (since two of these metal "are not friends" among themselves)
