Cause | Elimination Method |
Insufficient braking performance | |
Leakage of brake fluid from the wheel cylinders of the front or rear brakes | Replace bad parts of wheel cylinders, wash and dry pads and drums, bleed the hydraulic drive system |
Air in the brake system | Remove air from the system |
Damaged rubber seals in the master cylinder | Replace seals and bleed system |
Damaged rubber brake hoses | Check hoses, replace if damaged |
Incomplete release of all wheels | |
No free play on the brake pedal | Adjust pedal free play |
Clogged compensation hole in the master cylinder | Clean the hole and bleed the hydraulic brakes |
Swelling of the rubber seals of the main cylinder due to the ingress of gasoline, mineral oils, etc. into the liquid. | Thoroughly flush the entire system with brake fluid, replace damaged parts, bleed the hydraulic drive system |
Seizure of master cylinder piston | Check and, if necessary, replace the master cylinder, bleed the brake drive |
Braking of one of the wheels with the brake pedal released | |
Weak or broken brake pad return spring | Replace springs |
Seizure of the piston in the wheel cylinder due to corrosion or clogging | Disassemble the cylinder. Clean and wash parts, replace damaged |
Swelling of the sealing rings of the wheel cylinder due to the ingress of fuels and lubricants into the liquid | Replace the rings, flush the hydraulic brake system with brake fluid |
No clearance between pads and drum | Adjust parking and rear brakes |
Violation of the position of the caliper relative to the brake disc due to the loosening of the bolts of its fastening to the bracket | Tighten the mounting bolts; replace damaged parts if necessary |
Increased brake disc runout (more than 0.15 mm) | Grind the disc, if the thickness is less than 9.0 mm, replace it |
Skidding or pulling the car to the side when braking | |
1. Leakage of brake fluid in one of the wheel cylinders | Replace seals and bleed system |
Jamming of the piston of the wheel cylinder of brakes | Check and eliminate the jamming of the piston in the cylinder, if necessary, replace the damaged parts |
Blockage of any steel pipe due to a dent or blockage | Replace the tube or clean it and bleed the system |
Different tire pressure | Set normal pressure |
Incorrect front wheel alignment | Adjust wheel alignment |
Dirty or oily discs, drums and linings | Clean the brake parts |
Incorrect pressure regulator setting | Adjust the position of the pressure regulator |
Defective pressure regulator | Repair or replace pressure regulator |
Increased pressure on the brake pedal | |
Swelling of cylinder seals due to the ingress of gasoline, oils, etc. into the liquid. | Thoroughly flush the entire system, replace damaged rubber parts; bleed the system |
Screeching or screeching brakes | |
Weakening of the return spring of the rear brake pads | Check return spring and replace if necessary |
Out-of-roundness of rear brake drums | Waste the drums |
Lubrication of friction linings | Scrub the pads with a wire brush using warm water and detergent. Eliminate the causes of fluid or grease getting on the brake pads |
Wear of linings or the inclusion of foreign bodies in them | Replace pads |
Excessive brake disc runout or uneven wear | Grind the disc, with a thickness of less than 9 mm - replace the disc assembly with the front wheel bearing hub |
