When braking, the car pulls to the side:
- worn or dirty brake pads on one side of the vehicle;
- the piston of the working brake cylinder or caliper is stuck;
- brake pads with different properties are installed on different sides of the car;
- caliper mounting bolts not securely tightened;
- Worn or damaged suspension components.
Extraneous noise when braking:
- wear of the brake pad to the metal;
- corrosion of the brake disc or brake drum;
- Foreign objects are caught between the brake disc and the brake shield (stones).
Increased brake pedal travel:
- the main brake cylinder is faulty;
- air in the brake drive system;
- defective vacuum brake booster.
Light pressure on the brake pedal:
- air in the brake drive system;
- defective rubber brake hoses;
- the nuts of fastening of the main brake cylinder are unreliably tightened;
- the master brake cylinder is defective.
To stop the car, it is necessary to apply too much force to the brake pedal:
- defective vacuum brake booster;
- brake booster vacuum hose leaking;
- pinched or deformed brake pipes;
- the piston is stuck in the working brake cylinder;
- brake pads installed incorrectly;
- the type of brake pads does not match the required;
- contamination of brake pads;
- vacuum pump defective (diesel engines).
Vibration when braking:
- the runout of the brake disc exceeds the allowable limits;
- worn out brake pads;
- the brake shield or caliper fastening bolts are unreliably tightened;
- suspension wear.
Jamming brakes:
- the piston of the working brake cylinder is jammed;
- the hand brake mechanism is incorrectly adjusted;
- the master brake cylinder is defective.
