The brake is divided into drum brake and disc brake. The brake drum is installed on the wheel, and the brake pad is encapsulated inside. It rotates with the car wheel. Stepping on the brake is to make the brake pad friction with the seal drum inside.

Drum brake because it is sealed, heat dissipation is not good, long time driving braking effect will become worse, its cost is also low, the pump is easy to block, before driving need to check the brake more to ensure safety.

The disc brake is controlled by hydraulic pressure, and the brake caliper piston will push the brake pad to clamp the brake disc.

Brake oil is an important blood in the brake system. It has high boiling point, good lubricity and certain hygroscopicity. The water content of the brake oil should be checked when the car runs about 20000 km. If it exceeds the standard, it should be replaced in time to prevent brake failure.

Brake oil is classified by type: dot3 (alcohol ether type), DOT4 (ester type), dot5.1 (borate ester type).

In the brake system, brake disc, brake pad, brake fluid, piston / dust cover, spring plate, guide pin / dust cover, wheel hub / shaft head, brake oil pipe, etc. are vulnerable parts, which need to be checked during maintenance to ensure safety.

Due to different road conditions, the quality of oil and brake pads are different when the car is driving. More attention should be paid to the inspection and maintenance of brake maintenance, which can reduce the occurrence of accidents.

1. Check the thickness of the brake pad. Generally, it needs to be replaced when it is less than 3mm. There are also special testing tools.

2. The brake cylinder is maintained with lubricating oil, and many repair shops use butter for maintenance. After a long time, it is easy to dry up, and the longer the time, the limited activity. Now there are professional brake pump grease, can play a good role in protection.

3. Clean the brake disc with brake depth cleaning agent, which can reduce noise and ensure uniform heat dissipation of the brake.

4. The brake oil has certain hygroscopicity, and it needs to be replaced in time when the water content exceeds the standard, so as to ensure the driving safety.

Before driving, the car owner should check the amount of brake oil to see if it is lower than the minimum scale line. It is necessary to ensure that the oil is sufficient. If there is a lack, it indicates that there is a fault; The thickness of some brake pads can be seen from the outside, while others can only be seen when they are lifted up

If you hear abnormal noise while driving, you should go to the store to check in time to ensure safety.
