Check of components of brake system

The dust being formed as a result of wear of frictional slips and accumulating on a surface of components of brake mechanisms, can contain asbestos hazardous to health. Do not blow off a dust the compressed air and do not inhale it! Do not use for rubbing of components of brake system solvents on the basis of gasoline!

Besides the regular procedures stipulated by the Schedule of routine maintenance (see. Undressed the Schedule of routine maintenance), a condition of brake mechanisms it is necessary to check each time at removal of wheels or at emergence of signs of violation of serviceability of functioning of brake system.

Signs of malfunctions in 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.

At identification of the fact of contact of indicators with brake disks of a block should be replaced immediately!

Any of listed below signs can point to potential defect of brake system:

    When braking the car loses course stability (there is a withdrawal in one of the parties); During braking brake mechanisms publish squeal or a scratch; Excessively the course of a pedal of a foot brake increases; When squeezing a brake pedal the pulsations which have not been connected with operation of ABS are felt; Are observed leakages of brake liquid (usually on an internal surface of wheel assemblies).

In case of detection at least one of these signs immediately examine brake system.

Brake lines and hoses

In brake system steel brake tubes, except for the flexible reinforced hoses at forward wheels and as connections at the back bridge are generally used. Regular survey of all these lines is very important.


    Tire out the car on a platform / a viewing hole, or поддомкратьте it and hang out on props. Remove wheels. Attentively examine all brake lines and hoses on existence of signs of damages, wear, destruction as a result of aging of a material, traces of leaks, bends, twisting and other deformations, to the person attention giving to places of connection of flexible hoses to supports / to wheel cylinders of brake mechanisms. Estimate reliability of a tightening of all fixture, including homutny and shtutserny connections.

In case of need use a mirror.

    Bending shlangovy sections of brake lines make sure of lack of signs of their hidden damages.

To braid hoses does not follow.

    Turning a steering wheel from an emphasis against the stop, make sure that hoses thus do not touch elements of a design of the chassis/suspension bracket/helmsman of drive/system of release, - in case of need make the corresponding corrections, or correct a route of laying of lines. Defective components replace (see. Head Brake system). Study on existence of signs of development of leaks/corrosion and mechanical damages of a surface of GTTs, wheel cylinders and the pressure valve regulator. Defective components replace.

Disk brake mechanisms

Replacement of brake shoes should be made in a set for both wheels of a forward axis of the car!

The support of each of brake mechanisms is equipped with two blocks, - internal and external. End faces of blocks are well looked through through special observation ports in the support case after wheel removal.

The assessment of residual thickness of blocks is made visually through the observation ports mentioned above. If frictional slips are worn-out over an admissible limit (see. Specifications to Head Brake system), it is necessary to make complex replacement of brake shoes.

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).


    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.

    By micrometer measure thickness of brake disks, then by means of a tsiferblatny measuring instrument (DTI) define size of their lateral palpation. Compare results of measurements to standard requirements (see. Specifications of Head Current leaving and service). If the thickness or size of lateral palpation any leaves disks abroad an admissible range, replace it (see. Head Brake system). If thickness of a disk in norm, estimate its general condition. Pay attention to such defects as deep scratches, furrows, teases, overheat traces, etc., in case of need remove a disk (see. Head Brake system) also send him to a pro-point. The worn-out or deformed spring clamps of blocks also are subject to replacement.

Drum-type brake mechanisms

Replacement of brake boots should be made in a set for both wheels of a back axis of the car!


    Remove brake drums (see. Head Brake system). Make careful cleaning of brake mechanisms with application of special cleaning structure.

At all do not blow off a brake dust from a surface of components the compressed air and do not inhale it - the dust can contain asbestos harmful to your health!

    Estimate residual thickness of frictional overlays of forward and back brake boots, check components on existence of traces of pollution by brake liquid and oil. If the frictional slip acts over heads of rivets less than on 1.6 mm, boots are subject to replacement in a set for brake mechanisms of both wheels (see. Head Brake system). It is necessary to replace boots also in case of identification of cracks, zapolirovanny to shine of sites of slips, or traces of hit of brake liquid.
    Make sure of correctness of connection and serviceability of a condition of all springs of assembly of the brake mechanism (see. Head Brake system), - the neglect replacement of the deformed or weakened springs is fraught with premature wear of boots as a result "prikhvatyvaniye" of brakes. Check assembly components on existence of traces of leakages of brake liquid. Having carefully hooked a finger or a small screw-driver, remove rubber boots from the wheel cylinder which is holding apart the top ends of boots. Identification of any signs of leaks in these parts demands carrying out immediate regenerative repair of assembly of the cylinder (see. Head Brake system). Also check on existence of traces of leaks brake hoses and their shtutserny connections.
    Carefully wipe internal surfaces of a drum the pure rags impregnated with methyl alcohol, - try not to inhale a brake dust. Examine a working surface of a drum on existence of cracks, задиров, traces of an overheat and other damages. If defects cannot be removed with a way of processing of a surface a fine-grained emery paper, it is necessary to give a drum for a pro-point to a car-care center workshop, or to replace (see. Head Brake system). Measure internal diameter of a drum. In case of need measure diameter of the boots planted in brake assembly (see in the same place), then, by subtraction of result of the second measurement from result of the first, define size of a working gap of the brake mechanism.
    Repeat procedure for components of the opposite brake mechanism. Establish into place drums, fix wheels and lower the car on the earth. Tighten wheel nuts with demanded effort.

Check of the parking brake


    Park the car on an equal horizontal platform, transfer RKPP/AT / a transfer case to neutral situation and release the parking brake, - the car should move manually without the resistance caused by operation of back brake mechanisms. Cock the lever of the parking brake on 1 click and repeat check, - the car should not move. Completely cock the lever of the parking brake: the maximum admissible length of a course of the lever should not exceed 10 clicks of a ratchet, otherwise adjust the parking brake (see. Head Brake system).
