GENERAL INFORMATION

Prevention

Before definition of malfunctions in the brake system check the angles of installation of forward wheels, a condition of tires and pressure in tires. With malfunctions in anti-blocking system of brakes repair of system needs to be made at service station.


REASON
ELIMINATION METHOD
The increased free wheeling of a pedal of a brake
Overlays of brake shoes are worn-out Replace brake shoes.
One of contours of the brake system is faulty Check tightness of hydraulic contours of the brake system.
The increased course and softness of a pedal of coupling
At the hydraulic brake system there is an air Remove air from hydraulic system of brakes.
The lowered level of brake fluid in a popolnitelny tank Bring the level of brake fluid to norm.
Remove air from hydraulic system of brakes.
Boiling of brake fluid which usually happens at high load of the brake system Replace brake fluid. Remove air from hydraulic system of brakes.
Low overall performance of brakes
The hydraulic system of brakes is untight Define and eliminate the 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 assembled.
By pressing a pedal of a brake it is necessary to put big effort
On overlays of brake shoes oil got Replace brake shoes.
Brake shoes not of the corresponding type are established Replace brake shoes.
The vacuum amplifier of brakes or leakage in a vacuum hose of the amplifier is faulty Check the vacuum amplifier of brakes and a condition of a vacuum hose and, at необходимос ти, replace them.
Overlays of brake shoes are worn-out Replace brake shoes.
When braking the car takes away aside
Uneven pressure in tires of wheels Check and, if necessary, bring to norm pressure in tires of wheels.
Uneven wear of tires Replace worn-out tires
On brake shoes on the one hand of the car oil got Replace brake shoes.
On the different parties of the car brake shoes with different material of friction are used Replace brake shoes.
Nedostatochnaya Square of contact of brake shoes with a brake disk Replace brake shoes.
Pollution of a support Clear the support surfaces interfaced to brake shoes.
Full or partial jamming of the piston in a support Replace a support.
Uneven wear of overlays of brake shoes Replace brake shoes and check smoothness of a piston stroke in a support.
Constant podtormazhivaniye of wheels
The compensation opening in the main brake cylinder is blocked Clear and, if necessary, replace internal details of the main brake cylinder.
Insufficient gap between a pusher and the piston of the main brake cylinder Check and, if necessary, adjust those a gap between a pusher and the piston of the main brake cylinder.
Brakes are heated at the movement of the car
The compensation opening in the main brake cylinder is blocked Clear and, if necessary, replace internal details of the main brake cylinder.
Insufficient gap between a pusher and the piston of the main brake cylinder Check and, if necessary, adjust those a gap between a pusher and the piston of the main brake cylinder.
Brake shoes are constantly pressed to a brake disk Check work of a support of brakes and, if necessary, replace it.
Strong vibration when braking
Brake shoes not of the corresponding type are established Replace brake shoes.
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 shoes are constantly pressed to a brake disk, at the same time the wheel is turned hardly
There is a corrosion in cylinders of brake supports Repair or replace a brake support.
Uneven wear of overlays of brake shoes
Brake shoes not of the corresponding type are established Replace brake shoes.
Pollution of a support of a brake Clear a support.
Jamming of the piston in a support Check a state and, if necessary, replace a support.
The hydraulic system of brakes is untight Define the place and eliminate leakage of hydraulic system of brakes.
Wedge-shaped wear of overlays of brake shoes
The support of a brake is established with a distortion in relation to a brake disk Check 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 when braking
The overlay of a brake shoe is completely worn-out Replace brake shoes.
There is an insignificant layer of a rust on brake disks After several braking noise has to be gone and not appear more.
Brake shoes not of the corresponding type are established Replace brake shoes.
The support of a brake is established with a distortion in relation to a brake disk Check correctness of installation of a support of a brake.
Pollution of a support of a brake Clear a brake support.
Emergence of strong vibration when braking on a pedal of a brake or a steering wheel
At strong braking the anti-blocking system of brakes works Repair is not required as this normal phenomenon.
Strong wear or buckling of brake disks Check a condition of brake disks and, if necessary replace them.
Bolts of fastening of a support are weakened Check and, if necessary, tighten bolts of fastening of a support.
At the movement of the car the control lamp of ABS burns
Tension in onboard network of the car less than 10 V Check tension in onboard network of the car.
Check that the control bulb of accumulator charging dies away after start of the engine.
Otherwise check a condition of a maple belt and the generator.
The anti-blocking system of brakes is faulty Check a condition of anti-blocking system of brakes for service stations.
