GENERAL INFORMATION

REASON
WAY OF ELIMINATION
Too big single way of a brake pedal
Frictional slips are in whole or in part worn-out
Replace brake frictional slips.
Failure of one of contours of braking Check braking contours on leakage of brake liquid.
The brake pedal far leaves by pressing and springs
Air in brake system Remove air from brakes.
Too little brake liquid in a leveling tank Add new brake liquid.
Frictional brake slips are behind strongly worn-out, the payment of the basis of a slip adjoins to a spring Replace frictional slips. Use firm frictional slips.
Production of steam. Occurs at strong loading, for example, when driving on the pass Replace brake liquid. Remove air from brakes.
Slayuoye should be pressed action of brakes, a brake pedal to the full
Pipeline leakage Tighten elements of connection of the pipeline or replace it.
Damage of a cuff to the main thing or wheel brake cylinder Replace a cuff. At damage of a cuff to the main cylinder replace internal details or the cylinder.
Damage of stationary rubber laying Repair a support.
Bad brake effect, despite strong pressing a brake pedal
Frictional slips are oiled Replace frictional slips.
The unsuitable or hardened frictional slip Replace frictional slips. Use only firm frictional slips.
The amplifier of braking is faulty Check usiliteltormozheniye.
Piston jamming Provide a free wheeling of a support.
Pollution of hydraulic system Clear, replace brake liquid.
Frictional slips are worn-out Replace frictional slips.
Brakes creak
Frictional slips are worn-out Replace frictional slips.
The consequence of atmospheric influences (humidity of air) is frequent It is not required any actions if the scratch is observed after long parking of the car at high humidity and after the first braking does not repeat.
Unsuitable frictional slip Replace frictional slips. Use firm frictional slips. Cover the slip basis with paste an anti-scratch.
The brake disk rotates not in parallel to a support Check a surface of a prileganiye of a support.
The polluted wells in a support Clean support wells.
The wrong installation of pistons in supports of back wheels Check 20-degree installation of pistons.
Brakes are blocked at easy braking
Frictional slips are not oiled Replace frictional slips.
The brake is tightened spontaneously
The compensatory opening in the main brake cylinder is littered Clean the main brake cylinder and replace internal details.
Too small gap between operating bar and the piston of the main brake cylinder Check a gap (work in repair shop).
Frictional slips do not separate from a brake disk, wheels hard turn a hand
Corrosion in cylinders of supports Repair a support, in case of need – replace.
Non-uniform wear of slips
Unsuitable frictional slip Replace brake slips. Use firm frictional slips.
The support is polluted Clean support wells.
Hard piston stroke Check piston installation.
Leakage of brake system Check tightness of brake system.
Pulsation of a brake pedal
Too big admission on thickness or lateral palpation of a brake disk Check palpation and the admission. Finish a brake disk or replace.
The brake disk rotates not parallel to a support Check a surface of a prileganiye of a support.
Functioning of anti-blocking system ABS The normal phenomenon does not demand any actions,
Vibration of brakes
Unsuitable frictional slip Replace frictional slips. Use only firm frictional slips.
Partial corrosion of a brake disk Carefully smooth out a disk a grinding block.
Lateral palpation of a brake disk Finish or replace a brake disk.
The brake pedal slowly falls by easy pressing
Malfunction of the main brake cylinder Replace the main brake cylinder.
Unilateral action of brakes
Pressure of air in tires does not correspond to the ordered Check pressure of air in tires and correct.
Unevenness of wear of tires Replace worn-out tires.
Frictional slips are oiled Replace frictional slips.
Malfunction of a suspension bracket of a wheel or steering Check
Razlinye types of slips on one axis Replace frictional slips. Use firm slips.
Bad contact of frictional slips Replace frictional slips.
The pipeline is littered Check brake pressure of all four brakes.
The polluted wells of a support Clean a surface of landing and directing surfaces of frictional slips in a support.
Corrosion in support cylinders Replace a support.
Non-uniform wear of frictional slips Replace frictional slips (both wheels).
Brakes heat up in the course of movement
The compensatory opening in the main brake cylinder is littered Clean the main brake cylinder and replace internal details.
Unsatisfactory idling of a pusher of the main brake cylinder Check existence of a sufficient gap between a pedal and a pusher and, in case of need, adjust.
Jamming of the brake piston or its tugopodvizhnost Restore passableness.
The brake pipeline is littered Clean трубопороводы, replace brake liquid.
Wrong adjustment of the parking brake Correctly adjust.
