Check of the brake system

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

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


1. The condition of components of the brake system, besides the regular, stipulated schedule of routine maintenance, checks, has to be estimated every time at removal of wheels or at emergence of signs of violation of functioning of the brake system. Blocks of disk brake mechanisms are usually equipped with the special indicators notifying on excessive wear of frictional slips characteristic squeal when braking.
2. The listed below symptoms 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) Excessively the course of a pedal of a foot brake increases;
d) When squeezing a brake pedal pulsations are felt;
e) Traces of leak of brake fluid take place (usually on an internal surface of disks of wheels and tires).

3. Weaken nuts of fastening of wheels.
4. The car also establish to Poddomkratta 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 removal of a wheel. 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 overlays of a priklepana or are pasted to a metal substrate which thickness should not be considered at measurement.

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

9. After blocks are taken from a support, clear them by means of special means and measure the residual thickness of slips by means of a ruler or a caliper with a vernier scale.

10. Measure by a micrometer thickness of brake disks. Compare results of measurements to standard requirements (see Specifications). If thickness any of disks leaves abroad admissible range, replace it (see the Head the Brake system). If thickness of a disk is normal, check its general state. 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 the Head the 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 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 also suspension brackets do not adjoin to acute angles of the components of a body, system of production of the fulfilled gases 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. Replace defective components (see the Head the Brake system).

Vacuum amplifier


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

Parking brake


Assessment of serviceability of functioning of the parking brake can be made by way of the parking of the car on the section of the road and fixing going under a bias its not movably parking brake at neutral position of the transmission. If the brake does not hold the car at raising of its lever on the required number of clicks, it is necessary to make adjustment (see the Head the Brake system).
