CAUSE | METHOD OF ELIMINATION |
Increased brake pedal travel | |
| Brake fluid leaking from the wheel cylinders of the brake mechanisms, with oil stains observed on the calipers or brake drums | |
| Wear of brake pads and insufficient travel of brake mechanisms | They can be eliminated by replacing the pads and cleaning the brake mechanism |
| Failure of one brake circuit is determined by the presence of brake fluid leaks | |
| Automatic brake pad clearance adjustment device does not work | |
| The working surfaces of the brake discs or drums are heavily contaminated, corroded or worn out | It is necessary to thoroughly clean the brake discs or drums or replace them |
Insufficient braking efficiency | |
| Oiling of brake pad linings | It is eliminated by washing and drying the pads |
| Seizure of pistons in wheel cylinders | It is eliminated by disassembling the cylinders and replacing the damaged parts or the entire cylinder assembly |
| Overheating of brake mechanisms during frequent and prolonged braking | In this case, you must stop immediately and cool the brakes |
| Damage to the sealing rings in the master brake cylinder | It is eliminated by replacing the sealing rings or the cylinder itself |
| Incorrect brake pads are used | |
| The brake booster is faulty | |
The brake pedal sinks and springs | |
| Air in the brake system or low fluid level in the reservoir | It is eliminated by adding fluid and removing air from the brake system |
| Formation of vapor locks in overheated brake fluid due to too high a water content in the brake fluid | It can be fixed by replacing the brake fluid |
Incomplete release of braking of all wheels | |
| No free travel of the brake pedal | A jammed vacuum booster valve requires replacement of the vacuum booster |
| Swelling of the master cylinder sealing rings | It is eliminated by replacing the rings |
Uneven brake application | |
| Uneven tire pressure | Eliminated by inflating cold tires |
| Uneven wear of tires on one axle | Eliminated by installing equally worn tires on one axle |
| Oiling of brake pad linings | It is eliminated by washing and drying the pads |
| Seizure of pistons in wheel cylinders | It is eliminated by disassembling the cylinders and replacing the damaged parts or the entire cylinder assembly |
Braking of one of the wheels with the pedal released | |
| Broken or weakened rear brake shoe tension spring | It can be fixed by replacing the spring |
| Piston jamming in wheel cylinder | Repair the wheel cylinder or replace it |
| Violation of the position of the caliper relative to the brake disc when loosening the mounting bolts | Eliminated by tightening the bolts |
Car skidding or pulling away when braking | |
| Piston jamming in wheel cylinder | Repair the wheel cylinder or replace it |
| Contamination or oiling of discs, drums and pads | Eliminated by thorough cleaning of brake parts |
| Front wheel alignment angles incorrect | It can be eliminated by adjustment |
| Different tire pressures | Eliminated by inflating cold tires |
Squeaking or vibration of wheel brakes | |
| Broken or weakened rear brake shoe tension spring | It can be fixed by replacing the spring |
| Ovality of brake drums | It can be eliminated by boring or replacing the drums |
| Oiling of brake pad linings | It is eliminated by washing and drying the pads |
| Brake pad wear | Complete replacement of brake pads is required |
| Excessive brake disc runout or uneven wear | It can be eliminated by regrinding or replacing the disc |
