Check of brake system

Remember that developed when functioning brake mechanisms the dust can contain extremely unhealthy the person asbestos. At all do not blow off a dust the compressed air and do not inhale it, at service of mechanisms put on a protective mask or a respirator. At all do not use for rubbing of components of brake system gasoline or solvents on an oil basis - apply only firm cleaners or methyl alcohol! Try to use at replacement of blocks only components not containing asbestos.

The present Section is devoted to checks only disk (forward and back) brake mechanisms. More detailed illustrative material in Head Brake system.


1. The condition of components of brake system, besides regular, stipulated by the schedule of routine maintenance, checks, should be estimated each time at removal of wheels or at emergence of signs of violation of functioning of brake system. Blocks of disk brake mechanisms are usually equipped with the special indicators notifying on excessive wear of frictional slips by characteristic squeal at braking.
2. The symptoms listed below can be a sign of malfunction of components of brake mechanisms:

a) When braking the car loses course stability (there is a withdrawal in one of the parties);
b) During braking brake mechanisms publish squeal or a scratch;
c) The course of a pedal of a foot brake excessively increases;
d) When squeezing a brake pedal pulsations are felt;
e) Traces of leakage of brake liquid (usually on an internal surface of disks of wheels and tires) take place.

3. Weaken nuts of fastening of wheels.
4. To Poddomkratta the car also establish it on props.
5. Remove wheels.
6. The support of each of brake mechanisms is equipped with two blocks, - internal and external.
7. End faces of blocks are well looked through through a special observation port in the support case, and also from end faces of the last after wheel removal. The assessment of residual thickness of a frictional overlay of an internal block is made visually through the observation port mentioned above. If slips are worn-out over an admissible limit (see. Specifications), it is necessary to make complex replacement of brake shoes.

Remember that frictional slips приклепаны or are pasted to the metal substrate which thickness should not be considered at measurement.

8. If visually to estimate residual thickness of blocks it appears inconveniently, or there is a need for more detailed survey of blocks, remove a support (ы) and take blocks for more detailed studying (see. Head Brake system).

9. After blocks will be taken from a support, clear them by means of special means and measure residual thickness of slips by means of a ruler or a calliper with a noniusny scale.

10. By a micrometer measure thickness of brake disks. Compare results of measurements to standard requirements (see. Specifications). If the thickness any leaves disks abroad an admissible range, replace it (see. Head Brake system). If thickness of a disk in norm, check its general condition. Pay attention to such defects as deep scratches, furrows, teases, overheat traces, etc., in case of need remove a disk and send him to a pro-point (see. Head Brake system).

11. Before establishing to the place of a wheel, examine all brake lines on existence of signs of damages, wear, destruction as a result of aging of a material, traces of leaks, bends, twisting and other deformations (in particular near points of connection of flexible brake hoses to supports of brake mechanisms). Check reliability of fastening of hoses collars. Make sure that any of brake hoses systems of production of the fulfilled gases and a suspension bracket (do not adjoin to acute angles of the components of a body located in the neighbourhood, at any provisions of a steering wheel). In case of need make the corresponding repair or correct a route of laying of lines. Defective components replace (see. Head Brake system).

Vacuum amplifier


1. Check of serviceability of functioning of the vacuum amplifier of brakes is made from a driver's place.
2. At completely squeezed out pedal of a foot brake start the engine, - the pedal should fail a little more.
3. At the working engine several times squeeze out a pedal of a foot brake. The size of a course of a pedal should remain a constant.
4. Squeeze out a pedal, muffle the engine and continue to hold a pedal pressed during about 30 more seconds, during which it should not neither fail below, nor rise.
5. Again start the engine, let's to it work for about a minute, then again muffle. Again several times firmly squeeze out a pedal, - the size of a course should be reduced with each muscleman.
6. In case of negative result of the described check the servo-driver of the vacuum amplifier of brakes is subject to regenerative repair or replacement (see. Head Brake system).

Parking brake


The assessment of serviceability of functioning of the parking brake can be made by a way of a parking of the car on a site of the road going under a bias and fixing by its motionlessly parking brake at the neutral provision of a transmission. If the brake does not hold the car when raising its lever on demanded number of clicks, it is necessary to make adjustment (see. Head Brake system).
