Pumping brakes with ABS and ASC. Self-pumping brakes by car with ABS: step-by-step instruction

Pumping brakes has never been something very complex and problematic for motorists, the fulfillment of this work took an average of 1.5-2 hours. However, with the advent of cars with the ABS system, the task was significantly complicated, and the question of how to pump the brakes with ABS, most drivers will not be able to answer.

Process pumping brake system With ABS, it is impossible to be called time-consuming or via Chur complicated, the whole problem is that it is necessary to know the sequence of doing this work and then everything will turn out. Today I will tell you how to properly pump the brakes with the ABS system at home without any help.

How to lean brakes with ABS - Step-by-step instructions

There are two types of ABS systems that are pumped differently. Their differences are in the location of the nodes and the principle of action.

The first type ABS includes: pump, hydroklapan block and hydroaccumulator. Such a scheme of the ABS is considered the simplest, therefore it is pumped up almost as an ordinary brake system.

In order to pump the brake system with ABS, follow these items:

  1. Make a visual inspection of the main system block.
  2. Find a fuse that is responsible for the work of all aBS systems And remove from the nest. Thus, you turn off the system completely.
  3. Find the fitting and pumping RTC. Unscrew it and proceed to pumping.
  4. Pumping brakes with ABS is performed when squeezed pedal to check the action Turn on the ignition, the ABS fault indicator will turn on the instrument panel.
  5. Turn on the pump and wait until the air is completely out of the system.
  6. When the bulb goes out - this will mean that the system is pumped correctly.

Brakes with ABS second-type, in which the main nodes (pump, hydroaccumulator and hydroclap) are located in different places is pumped differently.

In order to pump the brakes with an ABS of this type, you need to have a special scanner, which reads the computer data running from the ABS unit. Given the cost of this instrument, it is unlikely to be cheaper to perform this work at home, perhaps it will be more profitable to go to a hundred.

In addition, such systems often have extra. Modules (ESP, SBC), which one way or another will need to be tested, and this can be done only in the service.

Brakes with ABS of this type are pumped as follows:

Note: This instruction how to pump brakes with abs contains general rules And recommendations, for each model of the car, this procedure may be insignificantly different.

First of all, you need to find a partner and reset the pressure in the system, which often reaches 180 and more atmospheres. With this pressure, it is not recommended to work with the system. In order to reset the pressure, you need to turn off the ignition and click on the brake for about 10-20 times. Disconnect the connectors on the tank with the DJ (brake fluid).

First pump the brakes of the front wheels:

  1. Turn off the ignition.
  2. Dress the hose for pumping fitting.
  3. Open the floor-turn fitting.
  4. Fully press the brake pedal and fix in that position. At the same time, you will see how to leave the TJ with bubbles.
  5. When bubbles are completed, tighten the fitting and release the pedal.
  1. Put the hose on the pumping fitting, unscrew it to the full turn.
  2. Sick the brake pedal "to the floor".
  3. Turn on the ignition, the brake pedal is not released.
  4. The pump will be down from the brake system all the air as soon as you see that there are no "bubbles" and liquid is coming Early break the fitting and release the pedal.

Now it came to pump the brakes of the rear left wheel:

  1. Again, put the hose on the fitting and unscrew it to the full turn.
  2. This time the brake pedal is not pressed.
  3. The included pump pumps "delivered" TZH.
  4. Next, press the pedal to half and tighten the fitting.
  5. Press the brake pedal and wait for the pump completely.
  6. Turn off the ignition, plug the connectors to the TJ tank.

Upon completion, check if there are no leaks, make sure the brake system tightness. Follow the brake fluid in the tank to required level. On this, pumping brakes with ABS can be considered complete. Collect the tool, wash your hands and check the operation of the brakes in motion. Be careful not to accelerate strongly, first check the brakes at low speed.

Pumping brakes with ABS is a very complex process that requires a combination of certain technical skills from motorists. Previously, before the emergence of cars with such a system, this question was not so serious, so it was done at home and took no more than one and a half hours of time. But with the development of the technology there was a problem of how to pump brakes with ABS.

The anti-lock system (ABS) does not allow blocking wheels with a sharp braking, while providing protection against loss of control over the car. The main task is to adjust the speed of rotation of all wheels. This is achieved by changing the pressure in the vehicle system, namely, with the help of pulses that go to the system control unit.

The principle of operation is based on the elementary laws of physics, more precisely on the power of friction. It is clear that the wheel contact is relative road coat is fixed, and since the strength of rest friction is more than the power of the slip of the sliding, anti-lock system Mainly equates the speed of movement of the wheels with the machine itself when braking.

The elements of the system include control valves that are in the main brake system highway, it is they obtaining pulses and regulate the pressure. Next, the sensors located on the wheel hubs that measure the speed of movement transmit this information to the main node. And finally the electronic unit Management, which makes decisions about the pressure in the brakes.

Instruction pumping

In order to carry out pumping ABS of the first type, you need to perform the following actions. First, conduct a visual inspection of the main block of the system. Secondly, turn off completely by removing the fuse. Thirdly, unscrew the fitting and pumping RTC and proceed directly to pumping. Do not forget that the whole process should occur when the pedal is squeezed, if you do everything correctly, the anti-lock fault indicator will light up when Ignoring. Next, you need to turn on the pump and wait until the air will be out of the system. The system will be pumped correctly if the bulb goes out.

The second type of ABS is pumped by another way, more complicated. To begin with, it is necessary to find a person who will help, because since such a system has all the elements are in different places, it will be impossible to make it one. The very first thing to do is reset the pressure, as it can reach 180 and more atmospheres. Recommended to do this by turning off the ignition and pressing about 10-20 times on the brakes. Also, turn off the connectors on the tank with the brake fluid. Pumping is performed first on the front wheels, and then on each rear wheel Separately, first on the right, and then on the left.

Let's start with the front wheels you need to: turn off the ignition, dress the hose on the pumping fitting, opening it no more than half the turn. Squeeze the brake pedal and firmly fix it in this position. Performing this action can be observed as the brake fluid with bubbles. After that, it is necessary to spin the fitting and let go of the pedal.

Next - rear right wheel. To begin with, again, wear the hose on the fitting, but this time to open it completely, on the whole turn. Squeeze to the end of the brake pedal. Include ignition without releasing the pedal. Then the pump himself will drop out of the brake system all the air, and as soon as you see that the brake fluid goes without bubbles, you can overlap the fitting and let go of the pedal.

And, at the end, the algorithm for pumping the brake of the rear left wheel. Stlikely, as with the previous wheel, you need to wear a hose to the fitting and fully open it. In this case, you do not need to squeeze the brake pedal. Meanwhile, the included pump rolls out the brake fluid along with air. The next thing to do is to press the pedal on half and tighten the fitting. Press the brake pedal and wait for some time until the pump stops. And at the end, turn off the ignition, not forgetting to connect connectors to the tank brake fluid. It is necessary to remember an important thing: during the procedure it is necessary to ensure that the pump worked without fluid, and it cannot work for more than two minutes. When the liquid does not have time to exit during this time, it stops and the entire cycle is repeated first.

At the end of the procedure, it is worth checking the tightness of the brake system, whether there are no flows in it. Also add in the tank brake fluid to a permissible level. On this, the whole process can be considered complete.

There are generally accepted precautions when pumping a car brake fluid. First - do not allow complete devastation expansion tankBecause of this, the hydraulics pump enters the air pump, which can be removed only in the workshop with special devices. The second - when replacing the brake hose, it is necessary to make pumping in the workshop, without which it is impossible to use the car as a means of movement.

Do not forget that each model of the car has its own characteristics of the brakes with aBS system, Therefore, before the start of the robots, it is worth carefully studying the management of management of your vehicle, since he necessarily has its own design features.

Features

From the very beginning put vehicle So that you can easily reach the brake system pumping. Let me remind you that it is on brake cylinders Each wheel.

ABS are two types: the first - consists of a pump, hydroclap and a hydroaccumulator. This type is considered the simplest, since pumping technology is the same as the standard braking system. The main feature The second type is that all its elements are located in different places of the car.


Based on these two types of ABS, it becomes clear that the principle of pumping each will differ significantly.

Video "Pumping brakes with ABS"

The videotape shows how to ride the brakes on the Mitsubishi Pajero's foreign car.

Good day, dear car enthusiasts! Among us, most likely there is no driver who at least once did not feel the feeling of helplessness at the time of braking. When the car continues to move, and not at all in the direction in which you want the driver. Skan.

Fortunately, engineering thought is not in place. The modern driver is armed with such a system as ABS. Let's stop in more detail on the system, and see whether the brakes are possible with the ABS with their own hands.

What is the ABS of the car

ABS (Anti-Lock Braking System) is an anti-lock system that prevents the blocking of the wheels during emergency braking.

The main task of ABS is: adjusting the speed of rotation of all wheels. This is done by changing the pressure in the brake system of the car. The process occurs using signals (pulses) from each wheel sensor, which is entered into the ABS control unit.

The principle of the anti-lock system
The spat of the car's wheel contact is located in relative immobility towards the roadway. In physics on the wheels there is a so-called. The strength of friction rest.

Taking into account the fact that the friction force of rest is more than the force of friction of sliding, with the help of the ABS, an effective slowdown of the rotation of the wheels with a speed, which corresponds to the speed of movement of the car at the time of braking.

At the time of the beginning of the braking, the anti-lock block system starts constantly and fairly accurately determine the speed of rotation of each wheel, and synchronizes it.

Anti-lock system device
We will give the main components of ABS:

  • sensors installed on the wheel wheel hubs: speed, acceleration or deceleration;
  • management valves installed in the main brake system highway. They are the components of the pressure modulator;
  • the electronic unit control abs. His task, receiving a signal from sensors and control of the work of the valves.

Pumping brakes with ABS taking into account the characteristics of the system

Pumping brake system with ABS will require you to have certain technical skills. In addition, it will not be superfluous to study the manual on the device and maintenance of the brake system of your car.

Features of pumping brakes with ABS

  • in cars, in which in one node are placed: a hydroclap block, a hydroaccumulator and pump, replacing the brake fluid and pumping the brake system with the anti-lock system is made similarly, you need to turn off the system by the method of the fuse notch. Pumping in the contours is performed when the brake pedal is pressed, the RTC dumped fitting should be turned away. The ignition is turned on and the pump drives out the air from the contour. Pumping fitting and brake pedal is released. Furious light bulb - evidence of the correctness of your actions.
  • Pumping the brake system with an ABS in which the hydrodul with valves and the hydroaccumulator are separated by separate nodes, is carried out using a diagnostic scanner for the eating of information from the ABS ECU. It is unlikely that you have. Therefore, pumping brakes with ABS of this type is most likely to be done by you to a hundred.
  • Pumping brake system with ABS and with electronic systems Activation (ESP or SBC) is made only under service.

How to pump brakes with abs

It is important! It should be remembered that the pressure in the brake system reaches 180 atm. Therefore, to exclude the emission of brake fluid, before disconnecting the brake lines from any system with ABS, it is necessary to discharge the pressure of the pressure. For this, when the ignition is turned off, press the 20th on the brake pedal.

Brake System Pumping Technology with ABS

Pumping brakes with ABS, like pumping the usual brake system, is performed with an assistant. Turn off the ignition (position "0"). Disconnect connectors on the brake fluid tank.

Brakes of the front wheels:

  • wear a hose on a groan fitting;
  • open a fitting on turnover;
  • the brake pedal is squeezed until it stops and is kept in the squeezed position;
  • we observe the output of the "delivered" mixture;
  • spin the fitting and let go of the pedal.

Rear Right Wheel Brake:

  • wear a hose on the pumping fitting, unscrew it for one turnover;
  • press the brake pedal until it stops, turn the ignition key to the "2" position. At the same time, the brake pedal is held in the pressed position;
  • the operating pump will be fused the air from the system. That is, as soon as the brake fluid begins to go out without air bubbles, overlapping the fitting and let go of the brake.

Rear left wheel brake

  • the hose is put on the fitting and unscrew it by 1 turnover;
  • Do not press the brake pedal;
  • the working pump pushes the "delivered" mixture;
  • press half on the brake pedal and wrap the fitting;
  • let go of the pedal and wait for the full stop of the pump.

AT reverse order: Ignition key to "0", connect the connectors to the brake fluid tank, check the tightness of the brake system (see the ABS fault indicator).

In this article we will tell how to properly pump brakes with ABS.

Signs of need for pumping brakes with abs

The anti-lock brake system also enjoys air. Since the contour of such a brake system is hydraulic, the air significantly worsens its performance. The determination of air accumulation in the brake system circuit is performed quite easily. If the recoil of the brake pedal when pressing began to be softer, it means that air appeared in the brake system.

The brake system with ABS air may appear in the following cases:

- Under repair hydraulic drive brake system;

- when replacing the caliper on one of the wheeled hubs;

- in the case of long standing of the car;

- in the case of the repair of various braking vehicles of the vehicle;

- When replacing the entire volume of brake fluid in the circuit.

The modern anti-lock system consists of the following main components:

- hydroaccumulator,
