What is the reason that the braking power of the automobile is insufficient and the braking efficiency is weakened?
fault phenomenon: brake pedal to the end, brake effect is not good; continuous braking, the effect is no improvement, and the pedal gradually increased.
fault phenomenon: pedal height normal, not soft, not sink, but the brake effect is not good. Reason: friction film and brake drum gap is too large or greasy.
, fault phenomenon: pedal position is very low, and then step, position can not rise, feel stiff. Reason: the main pump is blocked
fault phenomenon: continuous braking, pedal back up, braking effect improved. Reason: friction plate and brake drum gap is too large.
fault phenomenon: step on the brake pedal, the pedal does not rise, no resistance. Determine the reasons: check the brake fluid is missing; brake pumps, pipelines and joints are leaking; total pump, pump parts are damaged.
