Malfunction | Cause |
Braking begins when the pedal is moved almost to the floor (increased pedal travel) | Leak in the system |
Air in the system | |
Jamming of the mechanism of automatic adjustment of the rear brake | |
Damage to the twin dosing valve | |
Increased lateral play of the brake disc due to misfit or wear of the wheel bearings | |
"Topkaya" pedal | Air in the system |
Violation of the adjustment of the gap between the pads and the drum | |
Clogged tank lid vent | |
Brake pad deformation | |
Using a liquid with a low boiling point | |
Violations in the oil seals of the disc brake caliper | |
Insufficient braking performance | Air in the system |
Increased clearance between pads and drum | |
Oily pads or water ingress on them | |
Uneven fit of the pads to the drum | |
Leakage of brake fluid in the system | |
Contact with dirt, oil, grease and water | |
Wear of pads or pads beyond the allowable limit | |
Wear of elements of the main brake cylinder or elements of the working brake cylinder | |
Jamming of the lever mechanism of a brake pedal | |
Boiling disc brake caliper pistons | |
Unbalanced braking | Tire pressure variation |
Damaged pads or pads | |
Wheel cylinder damage | |
Violation of the adjustment of the landing of wheel bearings | |
Damage or wear to the surface of the drums | |
Wear of wheel cylinder elements | |
Weakening of the fastening elements of the working brake cylinders or the brake disc | |
Violation of the installation of wheels | |
Vibration brakes | Damaged pads or pads |
Drum or disc damage | |
Lining oiling | |
"tacking" brakes | Pedal misalignment |
Damage to the lever mechanism of the brake drive | |
Malfunction of master cylinder or wheel cylinder | |
Pad damage | |
Parking brake does not release | |
Clogged piping or dual dosing valve | |
Damaged brake pad return springs | |
Rear wheel lock | Insufficient braking efficiency of the front circuit |
Increased wear or abnormal tire pressure | |
Incorrect operation of the coupled metering valve (occurs when the brake pedal is pressed lightly) | |
Local wear on the surface of the brake linings | |
Low pressure in rear tires | |
Reducing the liquid level in the absence of traces of leakage along the elements of the system | Leak through the master cylinder into the vacuum booster of the system |
Broken vacuum booster spring | |
Pulsation of the brake pedal | Ellipsity or eccentricity of the brake drum |
Increased lateral runout of the brake disc | |
Uneven brake disc thickness | |
Spontaneous braking | Violation of the adjustment of system elements |
Violation of tightness of the vacuum amplifier |
