Brake system failure how to do?

Braking system for a car is one of the most important systems to protect pedestrians and their critical systems, and in case of failure of the braking system how to do?

1. Symptom: step on the brake pedal, the pedal does not rise, no resistance;

Analyzing reasons: Check whether the brake fluid deleted; brake cylinder, pipe joints and leaks oil; master cylinder, cylinder components is damaged;

2. Symptom: the brake pedal in the end, the braking effect is not good; continuous braking, no improvement effect, and gradually increased the pedal;

Analyzing reasons: mixed gas brake system;

3. Symptom: continuous brakes, pedal return increases, the braking effect is improved;

Analyzing the reason: the brake drum friction plate and the gap is too large;

4. Symptom: continuous brakes, increased pedal position, and sinking sense;

Analyzing the reason: oil;

5. Symptom: low pedal position; then step, the position can not be raised, stiff feeling;

Analyzing reasons: master cylinder plug;

6. Symptom: normal pedal height, not soft not sink, but not good braking effect;

Analyzing the reason: the brake drum friction plate and the gap is too large or oil;

7. Symptom: deviation brake;

Analyzing the reason: car skewed to the left, the right wheel brake was not working, and vice versa;

8. Symptom: vehicle travel for a distance, the brake drum (disc) fever;

Analyzing reasons: check the brake master cylinder, brake cylinder or tubing;

9. Symptom: brake pedal free travel is too small;

Analyzing reasons: to be adjusted;

10. Symptom: a slow recovery brake fluid level;

Analyzing reasons: Loosen the bleed screw, brake shoe return observe the situation. If the brake shoe return, it should clear the pipeline; if the shoe does not return, you should check the disintegration of the brake cylinder.
