10.15. The basic malfunctions of brakes
THE GENERAL DATA

The prevention

Before definition of malfunctions in brake system check up corners of installation of forward wheels, a condition of tyres and pressure in tyres. In the presence of malfunctions in antiblocking system of brakes system repair is necessary for making at servicing deport.


THE REASON
ELIMINATION METHOD
The increased free wheeling of a pedal of a brake
Overlays brake колодок are worn out Replace brake колодки.
One of contours of brake system is faulty Check up tightness of hydraulic contours of brake system.
The increased course and softness of a pedal of coupling
At hydraulic brake system there is air Remove air from hydraulic system of brakes.
The lowered level of a brake liquid in пополнительном a tank Finish level of a brake liquid to norm.
Remove air from hydraulic system of brakes.
Boiling of a brake liquid which usually occurs at high loading on brake system Replace a brake liquid. Remove air from hydraulic system of brakes.
Low overall performance of brakes
Негерметична hydraulic system of brakes Define and eliminate a place негерметичнос ти hydraulic system of brakes.
The sealing ring in the main thing or the working brake cylinder is damaged Replace a sealing ring.
If the sealing ring in the main brake cylinder is damaged, replace internal details of the main brake cylinder or the brake cylinder in gathering.
By pressing a brake pedal it is necessary to put the big effort
On overlays brake колодок oil has got Replace brake колодки.
Are established brake колодки not corresponding type Replace brake колодки.
The vacuum amplifier of brakes or негерметичность in a vacuum hose of the amplifier is faulty Check up the vacuum amplifier of brakes and a condition of a vacuum hose and, at необходимос ти, replace them.
Overlays brake колодок are worn out Replace brake колодки.
At braking the car withdraws aside
Non-uniform pressure in tyres of wheels Check up and, if necessary, finish to norm pressure in tyres of wheels.
Non-uniform deterioration of tyres Replace the worn out tyres
On brake колодки on the one hand the car oil has got Replace brake колодки.
On the different parties of the car are used brake колодки with a different material of a friction Replace brake колодки.
The insufficient area of contact brake колодок with a brake disk Replace brake колодки.
Support pollution Clear the surfaces of a support interfaced with brake колодками.
Full or partial jamming of the piston in a support Replace a support.
Non-uniform deterioration of overlays brake колодок Replace brake колодки and check up smoothness of a piston stroke in a support.
Constant подтормаживание wheels
The compensatory aperture in the main brake cylinder is blocked Clear and, if necessary, replace internal details of the main brake cylinder.
Insufficient backlash between a pusher and the piston of the main brake cylinder Check up and, if necessary, adjust those a backlash between a pusher and the piston of the main brake cylinder.
Brakes are heated at car movement
The compensatory aperture in the main brake cylinder is blocked Clear and, if necessary, replace internal details of the main brake cylinder.
Insufficient backlash between a pusher and the piston of the main brake cylinder Check up and, if necessary, adjust those a backlash between a pusher and the piston of the main brake cylinder.
Brake колодки are constantly pressed to a brake disk Check up work of a support of brakes and, if necessary, replace it.
Strong vibration at braking
Are established brake колодки not corresponding type Replace brake колодки.
There are traces of local corrosion on a brake disk Mechanically process a working surface of a brake disk.
Deformation of a brake disk Mechanically process or replace a brake disk.
Brake колодки are constantly pressed to a brake disk, thus the wheel is turned hardly
There is a corrosion in cylinders of brake supports Repair or replace a brake support.
Non-uniform deterioration of overlays brake колодок
Are established brake колодки not corresponding type Replace brake колодки.
Pollution of a support of a brake Clear a support.
Piston jamming in a support Check up a condition and, if necessary, replace a support.
Негерметична hydraulic system of brakes Define a place and eliminate негерметичность hydraulic system of brakes.
Klinoobraznyj deterioration of overlays brake колодок
The brake support is established with a warp in relation to a brake disk Check up correctness of installation of a support of a brake.
There is a corrosion in a brake support Clear traces of corrosion of a support.
Noise of brakes at braking
The overlay brake колодки is completely worn out Replace brake колодки.
There is an insignificant layer of a rust on brake disks After several braking noise should be gone and not appear more.
Are established brake колодки not corresponding type Replace brake колодки.
The brake support is established with a warp in relation to a brake disk Check up correctness of installation of a support of a brake.
Pollution of a support of a brake Clear a brake support.
Occurrence of strong vibration at braking on a pedal of a brake or a steering wheel
At strong braking the antiblocking system of brakes works Repair is not required, as this normal phenomenon.
Strong deterioration or коробление brake disks Check up a condition of brake disks and, if necessary replace them.
Bolts of fastening of a support are weakened Check up and, if necessary, tighten bolts of fastening of a support.
At car movement control lamp ABS burns
Pressure in an onboard network of the car less than 10 In Check up pressure in an onboard network of the car.
Check up that the control bulb of gymnastics of the accumulator dies away after engine start.
Otherwise check up a condition клинового a belt and the generator.
The antiblocking system of brakes is faulty Check up a condition of antiblocking system of brakes at servicing deport.
