The vibration of various elements of the car inevitably occurs during operation, when moving parts of the chassis and transmission are gradually wear out. But among such faults there is one dangerous problem - the beating of the steering wheel when braking. The stronger is twitching steering wheel After a sharp pressing of the brake pedal, the higher the probability of losing control and fly off the road at a decent speed. To avoid described emergency situationIt is worth examining the nature of the problem and how to solve it.
Where does the steering wheel beating?
Under the effect of the steering wheel, at the time of braking, spontaneous steering wheels jerks are meant in different directions. In particularly launched cases, the vibration is so strong that the driver falls in the literal sense to catch a car on the road. At speeds over 50 km / h phenomenon creates a real danger to passengers vehicle.
Since the rake by racks and ball tips is rigidly related to the front wheel hubs, the source of the problem must be sought in the chassis and braking system of the car. The main causes of vibration lies in various brake disc defects:
- the working part of the product is deformed and is a wave-like surface;
- due to the impact, the disk received damage and cracked;
- the spare part is initially defective or installed incorrectly.
The front brake discs are called the perpetrators not by chance. Worth it working surface Details slightly change the shape or get a defect, as after the shoe is triggered, the front wheels will begin to vive, repeating the rotation of the uneven element. An even stronger beats the steering wheel when braking at high speed, since the frequency of turns of the front wheels rises.
How wave deformation appears on the disk:
- In the course of the vehicle movement, the elements are repeatedly captured by pads and can be very hot.
- The temperature is distributed over the surface unevenly, respectively, the metal in different parts of the part is expanding more or less.
- If at the time of maximum warming the wheel falls into the puddle or snow, the metal is sharply cooled and retains a concave form.
- Brake pads, grabbing disk, make the wheel repeat the trajectory of rotation of the deformed surface. That is why the steering wheel begs at the time of braking.
The beating of the steering wheel is also manifested after the wrong attachment of the element or in the presence of a factory marriage, when the surface of the spare parts is originally curved.
Other reasons for vibration
The vibrations of the steering wheel, which are not associated with car jerks in different directions, are manifested for the following reasons:
- On the pads got one of technological fluids car, for example, transmission oil As a result of the wear of the gland. Having a significant viscosity, the lubricant is well held on any surface and violates normal work brakes harsh pressed Pedals.
- Wear out internal elements The steering rack, there was a significant backlash.
- The ball fingers of the steering tag came into disrepair.
- Disability of shock absorbers and front racks. The vibration on the ram is felt with sharp braking and simultaneously entering the turn.
Note. Motes associated with wear of ball supports and shock absorbers, also manifest on wheels rear axis. Most often on the pads fall brake fluidThe reasons are a malfunction of work cylinders and protested rubber cuffs.
Lead to deformation and subsequent vibration can a strong side blow of any wheel about high border (for example, due to ice or accident). The main load perceives the disk, the hub bearing and various suspension hinges. Any of the listed parts can get a crack and cause the steering wheel fluctuations during the braking process.
How does a malfunction diagnose?
To identify the disk of one of the front wheels, you will need a jack, anti-digit agents and a balloon key. Diagnostic procedure Next:
- Install the machine on a flat site and pull up to refusal hand brake. Additionally, inspire car shoes laid under any rear wheel.
- Raise the jackt front wheelSo that it hangs over the ground. On cars with front and fully drive Do not forget to translate the PPC lever to the neutral position.
- Rotate suspended rim. If you feel the jamming in a certain position, remove the wheel and make sure that the uneven disk turns about the pads, which is why it occurs strong vibration when braking.
The essence of diagnostics is simple: after triggering, the brake pads will move back smoothly to free the rotating surfaces. Before the extreme opened position, the lining must be pushing forcibly. If the metal working part is twisted, then the part will begin to get stuck between the pads.
Council. It is not a fact that the steering roaring in different directions are caused by the deformation of one disk. It is likely that the second element will also bent. Therefore, be sure to check for the presence of defects both of the front mechanism. At the same time, inspect the parts on the subject of cracks (especially after the side impact).
If the vibration does not cause deviations of the machine from the direct trajectory during the movement and does not force the beam, check the suspension and chassis elements. Vehicle beat on the examination ditch and jerks Try steering thrust for the back of the back. The performance of the shock absorbers is checked by the routing of the car up-down body weighing. After the application, the machine should rush not more than 1 time.
How to eliminate the beat?
When the steering wheel vibrates slightly on the car at the time of sharp braking, you can simply do nothing and ride further, taking appropriate security measures. They are to avoid too sharp slowdowns, otherwise the malfunction will be aggravated, and you risk losing vigilance and fly off the road.
If the beating is quite noticeable and really threatens the safety of people (vehicle passengers and pedestrians), the deformed disk should be changed or restored. The first way is associated with significant financial costs - spare parts for some car brands fairly expensive. In addition, the brake discs must be changed in pairs, otherwise at the moments of a sharp slowdown, the front of the car will begin to take away to the side.
Restoration of discs lies in the duct on a specialized machine. Equipment of advanced maintenance stations allows you to process the metal without removing the defective part from the machine. The procedure will be cheaper than the purchase and installation of new spare parts.
When when braking is shaking the car, regardless of the speed of movement, you need to search and troubleshoot anywhere else:
- Ensure that the operating lining of the rear and front wheels does not pour the brake fluid. The secondary sign is a decrease in its level in an expansion tank.
- Check the performance of the calipers and wheel cylinders of the brake system. The reason for the appearance of vibration is often becoming a jammed piston, and the leaks of the liquid - the undercut cuff.
- Sometimes the steering wheel begins to vibrate after replacing the pad. This symptom indicates low quality Installed spare parts.
In some cases, the vibration appears due to the receding brake linings. Malfunction is accompanied sounding Crossed or friction about metal.
Why when braking beats the steering wheel on the VAZ-2110? The main reasons for the vibration of the steering wheel when the brake is pressed from the speed of 80 km / h and less on Russian cars. The phenomenon is unpleasant, and completely deprives confidence in car control, because the next potential step is an unequal distribution of braking efforts, which can provoke a turn or coupling of the machine, or at all "brake loss".
Disks
Most frequent cause Batings of the steering wheel on the "dozen" and all VAZ machines - brake discs. They can even be new, but from the factory to have deviations in geometry, from here and problems. To check this visually when buying is almost impossible, you need to either look for branded parts, or try different parts, try to find discs with older machines.
With curves brake discs, beaten can not only in the steering wheel, but also in the brake pedal. But with strong wear, usually the vibration is mainly on the steering wheel. Naturally, when replacing the disks, it is necessary to immediately change the pads, check the caliper, there should be no hopted or varying degrees.
In principle, approximately 85% of cases of beating is precisely in disks and brake mechanism. It is also worth checking all caliper fixtures, maybe somewhere cut a bolt or it was unscrewed.
Wheels and chassis
VAZ-2110 and all family front drive He is experiencing an increased load on the front wheels. It is necessary to make balancing, as well as to control the condition of the nuts, the hub, and in general the chassis as a whole.
Quite often beats when braking the wheel itself. And not because of balancing, but due to broken bolts and holes. You can try to remove the wheel, rearrange it for one bolt forward in a circle, check the result. Some wound one revolution of the isol, it helps at least diagnose the problem. If for a short time the problem disappeared, then the case is in disks and fasteners.
Steering thrust swivel fists, ball supports, levers - all this needs to be twisted on a lift for a backlash. Again, when driving should carefully listen to the work of the suspension on the corners or irregularities. After the trip - check the same hubs for heating.
In principle, VAZ-2110 is such a car that if the steering wheel beats are not at speeds up to 90 km / h, then this is normal. At a higher speed, ride it in any case is dangerous, even if the chassis in perfect condition is the matter here as details and generally weak the strength of the car.
During the operation of the car, a lot of faults are detected. One of the frequent - beats the steering wheel when braking or in some kind of speed range. There may be many reasons, but the most important task is to identify valid. One diagnosis - steering wheel beating, and the malfunction can be hiding both in brake discs, or pads and in the car suspension.
The first thing you need to do is check the wheel balancing. Also visually check the rubber for cones. The collapse of the wheel alignment is adjusted. But before spending this procedure, you need to go through the entire suspension. The fact that the master on a hundred will not take to make a gathering camber with a broken suspension is correct. First, for the Master itself, this procedure will be too time-consuming. Secondly, for you, it will bring a positive result on short term. Thus, the steering beating will disappear, but not long.
Rate all the status of the suspension of your car, steering. There are often cases when worn ball bearings caused the cause of the steering wheel when braking or in the speed interval. If in the car all the suspension nodes have become unusable, then it is required to replace all worn items to new ones.
Why hits the steering wheel?
If none of the above reasons is real, then go further. Practically one hundred percent chance that the pads or discs are very worn, as a result of which the steering is felt when braking. Need to remove the wheel and check brake disk, appreciate its wear.
Raise the jack machine and remove the wheel. For the suspension, you need to substitute for the car support, in the extreme case - some strong funeral. In no case do not fit under the jack or car bricks. They are fragile, do not stand the load and eventually the car falls. Under rear wheels Put anti-tetting stops.
Dirt on the disk, cracks, curvature, - all these are the reasons for braking the steering wheel whipping. If the brake disk wear is too big, then remove and carry the boring to the boring. After installing the disks in place, the brake pads should be replaced. True, the boring can not always save. In half cases, get rid of the batting in the steering wheel when braking only installing new brake discs and pads.
Beats the steering wheel when braking and movement
If the steering is felt when moving at low speeds, then to start, take the brush and clean the wheels from the accumulated dirt. Dirt that poured on wheel disk, breaks the wheel balancing, as a result - the battery of the steering wheel. Cleaning the wheel, look at whether there is no dents on the disks. If there is, you need to fix it and carry out the wheel balancing. Check out steering rack, Wear steering, silent blocks.
When moving on high speeds The cause of the rudge of the steering wheel can be any of the above. Plus you can add hub bearings. To check the bearings, you need to shake the wheel in the vertical plane. A small backlash should be felt. When you click on the brake pedal, the backlash disappears. This is a symptom that bearings have strong wear And subject to replacement.
When braking, if the steering wheel beats, you can combine all the reasons, but the most likely - brake discs. On most cars, the installation of new brake discs and the pads brought a positive result. The beating of the steering wheel in the end disappeared, both when braking and when driving. If you keep the car suspension in good conditionT. similar problems You will experience infrequently.
Manage a good car comfortably during any maneuver and on any road. However, all this comfort passes with time, because the car is a car that has a property breaking over time. Moreover, each breakdown has its own "symptoms", prerequisites and consequences. Today we will deal with the situation when it hits the steering wheel when braking, more precisely, with those circumstances that can lead to it.
Why hits the steering wheel when braking: possible causes.
Cause 1 - curvature of brake discs.
What can be caused? Sharp heating and cooling named parts.
Methods of elimination: (on new) or their flow. Decide what to do will help inspection:
- remove the wheels;
- remove brake calipers;
- unscrew the disk mounting bolt to the hub;
- remove the brake disc;
- measure the thickness of the disk.
If the disk thickness is minimal (this is the most minimum value Manufacturers indicate on the disk), the protocate is not an idea - we perform a replacement. In other cases - We reanimate the old disk.
The reason 2 is faulty tips of steering.
What can be caused? Their wear is due to riding in bad "Koch-shaped" roads.
Methods of elimination: replacing tips to new ones.
In order to replace, it is necessary:
- unscrew the ball of the ball support and special tool Press out the hub;
- cut up the nut of the steering thrust and unscrew it by calculating the number of revolutions to turn the same number of revolutions to the same number of revolutions.
The reason is 3 - the silent blocks of the front steering levers are broken.
What can be caused? Constant overload of the car and driving through bad roads. Remedy methods: new or replacement of levers.
To replace the silent block you need:
- remove it from the car by reloading the lever fastening bolts to the car frame and ball support from the wheel hub;
- with the help of the press, the silent block discusses and presses the new one in his place.
The reason 4 is uneven wear of the front wheels.
What can be caused? Sharp braking when the wheels go to the UZ.
Remedy methods: Replace tires for new ones. To do this, contact the tire specialists.
Cause 5 - Finding the front wheels.
What can be caused? Tire wear or cargo dumping.
Remedy: Perform on special equipment. Here you can not do without necessary equipment, so this procedure Also requires an appeal to a hundred.
The reason 6 is the wear of the steering shaft crossbar.
What can be caused? Long-term operation of the car.
Methods for elimination: replace the steering cardan crossbar or replace the steering charter assembly. This replacement Produce as follows:
- disassemble steering column and unscrew the steering wheel cardan from the steering rack;
- remove the cardanchik and make a replacement of crosses or its entirely special tool.

Batting in the steering wheel, in general, very unpleasant, and for novice drivers, moreover, it is even dangerous. It is especially unpleasant when such a beating occurs when maneuvering or braking. And now we will try to deal with why the steering wheel beats when moving or braking and how to deal with it.
In fact, the reasons, because of which there can be a lot of steering wheel. Therefore, we only give the most common of them:
- drove the wheel balancing;
- broken wheel alignment;
- failure of the steering rack;
- hub malfunctions - wear hub bear;
- wear steering tips;
- behavished brake discs;
- wear ball support;
In principle, this list can be continued, but the causes of beating in the steering wheel, which are not listed here are more rare and characteristic of specific situations or auto models.
And so, if you have a knocked wheel balancing, you need to turn to a service station and carry out the balancing not only the front, but also rear wheels. You should also check whether the nuts are well tightened, with which the wheels are attached. Also, sometimes the beating in the steering wheel occurs when tire deformation, but this reason is easily determined by visual inspection.
Problems with a steering rack, this is an extensive horizon of opportunities and talk about it, you can still long. And the wear of the steering tips, manifests itself with characteristic sounds and other signs, and check the condition of the tips, not as difficult. The same thing relates to the wheel bearing. With its wear, you will hear a characteristic knock and a crunch that will tell you that the replacement of the bearing is quite navel.
As for the collapse of the wheels, other symptoms will also appear here. Side demolitions and other difficulties are likely when moving, rapid wear of the tires is possible, as well as a number of other wheels characteristic of the wrong collapse, signs.
Beats the steering wheel when braking
If the steering wheel beats when the brake pedal is pressed, especially at high speed, then the suspicion immediately falls on brake discs and brake system generally. And if everything is in order with the pads, you should intersee the brake discs themselves.
Most often, the cause of problems with brake discs becomes either strong overheating, or sharp supercooling. In the first case, the caliper is most likely to blame, because of which brake shoe It does not completely depart from the disk, which causes friction and of course heating. As for the hypothermation, this is the situation when you are after active braking, fly in a puddle or a snowy snowdrift. The disk heated by friction about the block cools sharply, which disrupts its geometry. In the future, the disk and the shoe interact unevenly, which starts to beat the steering wheel, and sometimes in the brake pedal.
There are two options for solving such a problem:
- replacement of brake discs;
- brake discs;
And if everything is more or less clear with the replacement, then a few words should be said about the brake disc. First of all, it should be remembered that the flow of brake discs is a temporary solution. And therefore, you need to go carefully in order to understand that the discs are time to replace it all. Also remember, even the most talented turner on a simple machine is unlikely to swirling the brake disc is evenly and correctly. This requires special equipment that today allows you to push discs without removing them from the car.
RESULTS
Actually, if you have when moving or when braking a car, it starts to beat the steering wheel, the fault arose, most likely, or in the steering system, or in the braking system. But, problems in the steering system are manifested, as a rule, not only when braking, and therefore it is worth paying attention to the move, and the braking system. True, there are cases when the breakdown hides where no one will think of it. For example, it happens that the cause of the beating in the steering wheel becomes the wear of a small chandelier in the steering column. And now, half of the car has been granted, a lot of money is invested in repair, and both beat in the steering wheel and beats. Therefore, before contacting the car repair shop, collect as many information about possible reasons Batings inherent in your car model.
