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

Possible causes of failure: Check if the brake fluid is missing; whether there is oil leakage at the brake cylinder, pipeline and joint; whether the master pump and the pump parts are damaged.

2. Fault phenomenon: the brake pedal is stepped on the bottom, the braking effect is not good; the continuous braking, the effect is not improved, and the pedal gradually rises;

Possible cause of failure: Gas is mixed in the brake system.

3. Fault phenomenon: continuous stepping on the brakes, the pedal return position is raised, and the braking effect is improved;

Possible cause of failure: The gap between the friction lining and the brake drum is too large.

4. Fault phenomenon: continuous stepping on the brakes, the pedal position is raised, and there is a feeling of sinking;

Possible cause of failure: oil leakage.

 

 

 

Brake disc overheating will affect the brake safety distance

5. Fault phenomenon: the pedal position is very low; if you step again, the position cannot be raised, and the feeling is hard;

Possible cause of failure: The main pump is blocked.

6. Fault phenomenon: the pedal height is normal, not soft and not sinking, but the braking effect is not good;

Possible cause of failure: The gap between the friction lining and the brake drum is too large or oily.

7. Fault phenomenon: brake deviation;

Possible cause of failure: If the car is skewed to the left, the right wheel will not brake, and vice versa.

8. Fault phenomenon: the car travels for a long distance, and the brake drum (disc) is hot;

Possible cause of failure: Check the master cylinder, brake cylinder or piping.

9. Fault phenomenon: the free travel of the brake pedal is too small;

Possible cause of failure: need to be adjusted.

10. Fault phenomenon: the brake fluid level rises slowly;

Possible causes of failure: Loosen the bleeder screw and observe the brake shoe return position. If the brake shoe is returned, the oil pipe should be cleared; if the brake shoe does not return, the brake cylinder should be dismantled.

 

 

Ceramic formula brake pads were first developed by Japanese brake pad companies in the 1990s, and were generally welcomed by markets such as Japan and North America. Ceramic brake pads have the advantages that traditional brake pads can't match, and will definitely become the development direction of the market.

 

Advantages of  Ceramic Brake Pad: 1. Stable friction coefficient. Generally, the friction coefficient of the brake pad increases with the temperature during the braking process of the car, and the friction coefficient is reduced to reduce the braking effect. The ceramic sheet has a friction coefficient of 0.45-0.55 at a temperature of 650 ° C, ensuring good braking performance. 2. long lasting. 3. The damage to the pair of parts is small. The inorganic material in the ceramic brake pad has less wear on the brake disc than the metal component in the semi-metal brake pad, and can achieve almost zero wear. 4. Low noise. Since the friction materials used in ceramic brake pads are mostly graphite, ceramic fiber, nitrile rubber powder, potassium carbonate and other inorganic materials, ceramic brake pads are much less noisy than semi-metal sheets in friction braking.
