CAUSE | SOLUTION |
Too much idle brake pedal |
| Faulty one brake circuit | Check the tightness of the brake circuits |
The brake pedal is squeezed away and springy |
| The air in the brake system | Bleed the brake system |
| Too little brake fluid in the expansion tank | Fill with new brake fluid, bleed the air |
| Blistering occurs most often as a result of severe stress, such as descents in the mountains | Replace brake fluid, bleed the air |
The braking effect decreases, the brake pedal is squeezed out to the end |
| Leaky pipeline | Tighten pipe connections or replace the pipeline |
| Damaged or cuff main brake cylinder wheel | Replace cuff from the master cylinder to replace the internal parts, if necessary, replace the brake master cylinder |
| Specially for disk brakes damaged stationary rubber sealing ring | Sort out brake |
Poor braking effect despite the strong pressure on the brake pedal |
| Zamasleny brake linings | Replace the brake pads |
| Unsuitable or hardened brake pads | Replace brake linings, brake pads set VW |
| Defective brake booster | Check the brake booster |
Specially for disk brakes are worn brake linings
| Replace the brake pads |
When braking vehicle pulls towards |
| Tire pressure is not OK | Check and adjust tire pressure |
| Tires worn unevenly | Replace worn tires |
| Zamasleny brake linings | Replace the brake pads |
| The brake pads of different types on a single bridge | Replace the brake pads. Set brake pads VW |
| Poor contact patch brake linings | Replace the brake pads |
| Specially for disk brakes of mine contaminated brake (saddles or frames) | Clean the installation site and guide surfaces in the brake mechanism |
| Corrosion in the brake cylinders | Replace brakes |
| Uneven wear on the brake linings | Replace the brake pads (on both wheels) |
| Especially for drum brakes severe stroke in the brake cylinder | Refurbish Brake Cylinder |
The brake is activated by itself |
| Goals scored compensation opening of the master cylinder | Clean the brake master cylinder, replace internal parts in the workshop |
| Too small gap between the operating rod and the piston of the master cylinder | Check clearance |
Brakes heat up during movement |
| Goals scored compensation opening of the master cylinder | Clean the brake master cylinder, replace internal parts in the workshop |
| Too small gap between the operating rod and the piston of the master cylinder | Check clearance |
| Specially for disk brakes scored orifice valve special reference | Clean the brake master cylinder, replace internal parts and replace the brake fluid |
| Especially for drum brakes weak return springs brake pads | Replace return springs |
Brakes rumble |
| Brake linings do not comply with the above | Replace brake linings, brake pads set VW |
| Specially for disk brakes: disc brake Fitting zakorrodirovali | Carefully align the disc grinding stone |
| Side brake disc battle | Bring or replace the brake disc |
| Especially for drum brakes are worn brake linings | Replace brake linings, brake pads set VW |
| The brake drum is not a round shape | Machined, if necessary, replace the brake drum |
Brake linings do not depart from the brake disc, wheel rotating tightly by hand |
| Specially for disk brakes: corrosion in the brake cylinders | Sort out brake, replace |
Uneven wear on the brake linings |
| Specially for disk brakes: the brake linings do not comply with the above | Replace brake linings, brake pads set VW |
| Dirty brake | Clean the surface of the brake |
| Difficult to move the pistons | Restore the ease of movement of the pistons |
| Leaky brake system | Check tightness of brake system |
The cone-shaped brake lining wear |
| Specially for disk brakes: the brake disc rotates parallel to the brake mechanism | Check the surfaces of the brake |
| Corrosion in the brake mechanism | Eliminate pollution |
| Poor working pistons | Check adjustment pistons (piston ring) |
The brakes squeak |
| Environmental influences (humidity) | No need to remove (if squeaking comes after a long standing machines with strong humidity, but then disappears after the first braking) |
| Especially length disc brake: brake linings do not comply | Replace brake linings, brake pads set VW |
| Brake disc brake mechanism not parallel | Check the surfaces of the brake |
| Contaminated with mines in the brake mechanism | Clean brake shafts |
| Kinked spring lock brake pads | Replace retaining spring |
| Elongated spring spacers | Pull spring spacers |
| Especially for drum brakes: brake pads fitting loosely | Replace the brake pads |
| Dirty brakes | Clean brake |
| Too relaxed return springs | Replace return springs |
The brakes pulsate |
| Powered ABS | Elimination does not require |
Specially for disk brakes:
side fighting or too large thickness tolerances of the brake disc | Check battle and tolerance, to bring the disk back to normal or replace |
| Brake disc is not parallel to the brake mechanism | Check the surfaces of the mechanism thermos |
| Especially for drum brakes: the surfaces of the disk to the brake drum is uneven, bending brake drum | Try to change discs each other; better machined brake drum bolted together with him on a turning wheel |
