| Symptom |
Possible reason |
|
When braking course stability of the car is broken
|
Tires (are pumped incorrectly up see. Head Routine maintenance of the car). |
| Adjustment of corners of installation of wheels (is broken see. Head Steering). |
| On one axis tires of a various standard size are established. |
| Passableness of brake lines or hoses (is broken see. Head Brake system). |
| The support of the brake mechanism (is damaged see. Head Brake system). |
| Weakened fastening of components of a suspension bracket (see. Head Forward suspension bracket). |
| Weakened fastening of a support of the brake mechanism (see. Head Brake system). |
|
During braking there are extraneous noise (a gnash or high-frequency squeal)
|
Frictional overlays of brake shoes of lobbies or back brake mechanisms are worn-out to substrate metal. Squeal is published by indicators of wear of blocks at a friction about brake disks. Immediately replace blocks (see. Head Brake system). |
Brake vibration takes place. (pedal pulsations)
|
|
On the models equipped with ABS of a pulsation of a pedal of a brake are a consequence of normal functioning of system |
|
Excessive cross-section palpation of a brake disk (takes place see. Head Brake system). |
| Parallelism of walls of a brake disk (is broken above an admissible limit see. Head Brake system). |
| Non-uniform wear of brake shoes owing to support jamming as a result of the wrong installation of a gap or dirt hit (takes place see. Head Brake system). |
| The brake disk (is faulty see. Head Brake system). |
|
The course of a brake pedal is excessively great
|
Partial violation of functioning of brake system (takes place see. Head Brake system). |
| Level of brake liquid fell in GTTs (see. Heads Routine maintenance of the car and Brake system). |
| Air got to hydraulic system (see. Heads Routine maintenance of the car and Brake system). |
|
For a stop of the car applying of excessively big effort to a brake pedal is required
|
The block of the vacuum amplifier of brakes (is faulty see. Head Brake system). |
| Partial violation of functioning of brake system (takes place see. Head Brake system). |
| Brake blocks/boots (are excessively worn-out see. Head Brake system). |
| The piston (and) a support (is jammed see. Head Brake system). |
| Frictional overlays of brake shoes (are greasy see. Head Brake system). |
| New brake shoes are established and were not earned extra yet - for extra earnings of blocks to disks time is required. |
|
Brakes "are taken"
|
There is no due return of GTTs pistons (see. Head Brake system). |
| Passableness of brake lines/hoses (is broken see. Heads Routine maintenance of the car and Brake system). |
| Adjustment of the parking brake (is broken see. Head Brake system). |
| Functioning of the mechanism of automatic adjustment of drum-type back brake mechanisms (is broken at the corresponding complete set) (see. Head Brake system). |
|
Uniformity of distribution of brake effort is broken
|
The vacuum amplifier of brakes (is faulty see. Head Brake system). |
| The mechanism of a pedal of a foot brake (is jammed see. Head Brake system). |
|
Softness of a course of a brake pedal takes place at its squeezing
|
Air got to hydraulic system (see. Head Brake system). |
| Weakened bolts of fastening of GTTs (see. Head Brake system). |
| GTTs (is faulty see. Head Brake system). |
|
The brake pedal fails to a floor practically without resistance
|
Excessively liquid level fell in the GTTs tank owing to leaks via the piston (and) supports, weakening of fastening or damage of hydraulic brake lines (see. Head Brake system). |
|
The parking brake does not provide reliable fixing of the car
|
Adjustment of the parking brake (is broken see. Head Brake system). |
| Are worn-out, or frictional overlays of boots of the mechanism of the parking brake (are polluted see. Head Brake system). |
