List of malfunctions

Malfunction
Its reason
Than to help
A.Avtomobil when braking withdraws aside 1. Non-uniform pressure in tires
2. Non-uniform profile of tires
3. Brake shoes became covered by dirt, were made oily or non-uniformly wore out
4. Directing in a support of the disk brake mechanism are covered with dirt or rusted
5. Prirzhavel the piston in a support of the disk brake mechanism or in the wheel brake cylinder
6. Brake shoes incorrectly adjoin to a drum
7. Brake disks have scratches or too thin
8. The deformed brake drums
9. The inflated brake hoses 		To modify on cold tires
To replace tires
To replace blocks
To clear

To clear of a rust or to replace


To check, if necessary to establish new brake shoes

To replace brake disks

To process on the lathe or to replace

To replace hoses

V.Tormoza creak 1. Blocks are picked incorrectly up
2. A dust and dirt on disk brake mechanisms or in drum-type brake mechanisms
3. See. And 4, 5, 7 and 8 		To establish original blocks
To remove blocks, to remove pollution
S.Tormoza knock and are blocked 1. See. And 5
2. Acting rivets of laying
3. See. And 8
4. Too weak returnable springs of brake shoes
5. Palpation of a brake disk 		To replace

D. One or all wheel brake mechanisms strongly heat up 1. The compensatory opening in the main brake cylinder is hammered
2. Is not present люфта between a brake pedal (a press bar) and the piston of the main brake cylinder
3. The rusted supports of the disk brake mechanism
4. The parking brake is not disconnected completely
5. The returnable spring (the drum-type brake mechanism) is broken 		To clean

To establish


To give to repair

To check cables of a brake drive and brake mechanisms of back wheels
To replace

E.Slishkom a big course of a pedal of a brake, a pedal is pressed softly and springs 1. Air in brake system
2. A leakage in brake system
3. Faulty main brake cylinder
4. At strong load of brake system (overheat) formation of vials of steam in too old brake liquid
5. See. And 5 		To remove air from brake system
To inspect on tightness
To replace
To replace brake liquid
F. Ill effect of brakes at big effort to a pedal 1. Normal course of a pedal: blocks are covered with oil or glazed over
2. Short course of a pedal: the amplifier of a brake drive is faulty
3. Long course of a pedal: one brake contour does not work because of a leakage 		To replace

To check, replace the damaged details

G. The parking brake operates unilaterally or too poorly 1. See the description under And
2. The rusted cable of a brake drive
3. The adjusting mechanism is faulty 		To replace
