Check of brake system

The dust formed as a result of deterioration of overlays and accumulating on components of the brake mechanism, can contain hazardous to health asbestos. Do not blow this dust by means of compressed air and do not inhale it! Do not use for removal of a dust solvents on the basis of gasoline.

Except checks through the established intervals of time a condition of brake mechanisms it is necessary to spend each time at removal of wheels or at occurrence of signs of malfunction in brake system.

Signs of malfunctions in brake system

Disk brake mechanisms have the built in indicators of deterioration of the frictional overlays, signalling that deterioration of overlays has reached critical size. Thus overlays should be changed immediately, differently brake disks will be damaged also by it expensive repair is required.

Any of listed below signs can specify in potential defect of brake system:

    At squeezing of a pedal of a brake the car "withdraws" in one party; Brake mechanisms at braking publish scraping or squealing sounds; The brake pedal has an excessive course; The brake pedal pulses (it normally only at system ABS work); Leaks of a brake liquid (usually appreciable tyres on an inside or wheels) are observed.

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

Brake lines and hoses

In brake system basically steel brake tubes, except for the flexible reinforced hoses at wheels are used. Regular survey of all these lines is very important.


    Park the car on an equal platform. Поддомкратьте the car also establish it on props then remove wheels. Check up all brake lines and hoses on presence of cracks and attritions in their external covering, leaks, swellings and deformations. Check up brake hoses in forward and back parts of the car on presence of signs of a softening, cracks, deformations or deterioration as a result of a friction about other details. Check up all штуцерные connections on presence of signs of leaks and make sure of reliability of all fixture of brake lines. Bend hands in one and other parties a brake hose to reveal damages. To braid hoses does not follow. Turn a steering wheel to the right and to the left against the stop. Make sure that hoses thus do not touch elements of a design of the car. At detection of leaks of a liquid from brake lines or their damages of leak it is necessary to eliminate immediately. For more detailed description of procedure of repair of brake system address to the Head Brake system.

Check of a thickness brake колодок and disks


    Поддомкратьте the car also establish it on props then remove a corresponding wheel.
    Check up a thickness brake колодок and through an aperture in a support of the brake mechanism.
    Deterioration limit колодки the thickness is considered of 5.0 mm, in this case pad it is necessary to replace (the Brake system) see the Head.

As a rule, 1 mm of deterioration of a frictional overlay brake колодки corresponds, at least, 1000 km of run at adverse service conditions. In usual conditions of an overlay are erased much more slowly.

    In case of doubt in correctness of measurement remove brake колодки and measure their thickness by a calliper. If deterioration degree is already reached, replace brake колодки. It is necessary to replace all 4 колодки wheels of one axis, even in the event that one has worn out only колодка. Check up supports of the brake mechanism on presence of leaks. At detection of leaks urgently repair a support. Visually check up brake disks with internal and an outer side on presence of furrows, a rust, cracks, if necessary replace disks.
    Measure a thickness of brake disks in several places by means of a micrometer or a special calliper. It is possible to measure also a thickness of a brake disk by a usual calliper, having enclosed from its each party a lining of known size (for example, two coins), and then having subtracted from the measured value a thickness of a lining.
    Compare minimum of the received results to requirements of Specifications to the Head Brake system. If the deterioration border is reached, replace necessarily both brake disks of wheels on one axis. Also it is necessary to replace a brake disk and at the big cracks or deep furrows. In summary check up integrity of indicators of deterioration колодок and a thickness of boots of a lay brake. Replacement of boots is recommended to be made, if through a control aperture in a disk 10 coils of a carving are visible. Establish wheels and lower the car on the earth.

Check and adjustment of a lay brake

Site of an adjusting nut


    Park the car on an equal surface and release a lay brake. The car should move manually, action of brakes should not be felt. Cock the lever of a lay brake. If wheels are not blocked after four clicks, adjust a lay brake in the image described more low. Remove wheels and by means of a screw-driver unscrew a regulator so that the brake disk has been blocked. Then tighten a regulator prior to the beginning проворачивания a brake disk. Repeat procedure on the second back wheel. Establish wheels. Check up a stock of a course of the lever of a lay brake. For this purpose will hang out back wheels and pull the lever before the first click. Tighten an adjusting nut on the lever of a lay brake access to which is available through an aperture in the central console until the brake will not start to seize. Release a lay brake and cock it again. After 1 - 4 clicks of a wheel should be blocked.
