MALFUNCTION
|
REASON
|
| Braking begins when moving pedal almost to a floor (the increased working course of a pedal) | Leak in system |
| Availability of air in system |
| Jamming of the mechanism of automatic adjustment of a back brake |
| Damage of the coupled dosing-out valve |
| Raised lateral люфт a brake disk because of violation of landing of wheel bearings or their wear |
| "Fenny" pedal | Air in system |
| Violation of adjustment of a gap between blocks and a drum |
| Contamination of a ventilating opening of a cover of a tank |
| Deformation of brake shoes |
| Liquid use with a low boiling point |
| Violations in epiploons of a support of a disk brake |
| Insufficient efficiency of braking | Air in system |
| The increased gap between blocks and a drum |
| Zamaslivaniye of blocks or water hit on them |
| Non-uniform prileganiye of blocks to a drum |
| Leakage of brake liquid in system |
| Hit on a surface of overlays of dirt, oil, konsistentny greasing and water |
| Wear of slips or blocks over an admissible 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 of pistons of a support of a disk brake |
| Unbalanced braking | Disorder of pressure of air in tires |
| Damage of slips or blocks |
| Damage of the wheel cylinder |
| Violation of adjustment of landing of wheel bearings |
| Damage or wear of a surface of drums |
| Wear of elements of the wheel cylinder |
| Weakening of elements of fastening of working brake cylinders or basic disk of a brake |
| Violation of installation of wheels |
| Vibration of brakes | Damage of slips or blocks |
| Drum or disk damage |
| Zamaslivaniye of slips |
| "Prikhvatyvaniye" of a brake | Violation of adjustment of a pedal |
| Damage of the lever mechanism of a drive of brakes |
| Malfunction of the main cylinder or wheel cylinder |
| Damage of blocks |
| Not растормаживается parking brake |
| Contamination of pipelines or the coupled dosing-out valve |
| Damage of returnable springs of brake shoes |
| Blocking of back wheels | Insufficient efficiency of braking of a forward contour |
| The increased wear or abnormal pressure in tires |
| Incorrectness of operation of the coupled dosing-out valve (it is shown by weak pressing a brake pedal) |
| Local developments on a surface of brake slips |
| The lowered pressure in tires of back wheels |
| Decrease in level of liquid in the absence of leak traces on system elements | Leak on the main cylinder in the vacuum amplifier of system |
| Breakage of a spring of the vacuum amplifier |
| Pulsation of a brake pedal | Ellipsnost or eccentricity of a brake drum |
| The increased lateral palpation of a brake disk |
| Unevenness of thickness of a brake disk |
| Spontaneous braking | Violation of adjustment of elements of system |
| Violation of tightness of the vacuum amplifier |
