How To Maintain The Unstable Brake System?

[Catalog:News] [Date:2021-1-29] [Hits:] [Return]

The braking system is very important for the safety of the car. But the maintenance of the brake system is often ignored by the driver. It is often found that the brake system is not working properly before the brake system is overhauled. In this way, it is very likely that the sudden failure will lead to the failure of the brake and cause great disaster. Therefore, only frequent maintenance of the brake system can ensure the normal operation of the brake system, and then ensure driving safety. The brake system of cars and minivans mainly uses brake oil to transfer braking force, while the pneumatic brake system is used for large buses and heavy trucks. There are different maintenance methods for different braking systems.

Brake oil is a key link in the automobile braking system, which is related to the personal safety of car owners. Although it is difficult for car owners to identify the authenticity of brake oil by naked eyes, there are five points for car owners to pay attention to when using brake oil

1、 Do not mix different types and brands of brake oil. Due to the different formulation, the mixed brake oil will cause the decrease of brake oil performance.

2、 When the brake oil absorbs moisture or impurities, it should be replaced or filtered in time, otherwise it will cause insufficient braking pressure and affect the braking effect. This is particularly important because the weather in South China is generally humid.

3、 If the vehicle runs normally for 40000 km or the brake oil has been used continuously for more than 2 years, the brake oil is easy to deteriorate due to long service time, so it should be replaced in time.

4、 In normal driving, if the brake is light or heavy, the brake oil should be replaced in time, and the brake system should be cleaned with alcohol before replacement.

5、 When the vehicle brake deviates, the brake system should be checked comprehensively. If it is found that the rubber cup of the slave cylinder expands too much, it indicates that there may be a problem with the quality of the brake oil. At this time should choose a better quality brake oil replacement, while replacing the cup.

Generally, the wear of front brake shoes is relatively fast, and the service time of rear brake shoes is relatively long. In the daily maintenance, we should pay attention to: under normal driving conditions, check the brake pads every 5000 km, not only check the remaining thickness, but also check the wear status of the shoes, whether the wear degree on both sides is the same, whether the return position is free, etc. in case of abnormal conditions, we must deal with them immediately, and the brake must not be replaced until the friction material is worn out. Some vehicles are equipped with brake pad alarm function. Once the wear limit is reached, the instrument will give an alarm to prompt replacement.

1. Brake pad replacement cycle. Usually, we judge whether the brake warning light on the instrument panel is on or not, but this is the bottom line. In some cars, the warning light is on only after the brake shoes have been completely worn. At this time, the metal base of the brake pad and the brake disc are in the state of iron grinding, and bright iron chips will be seen near the rim of the tire. Therefore, it is necessary to check whether the brake pads can be used and replace the brake pads close to the bottom line of service life in advance.

2. Daily maintenance of brake system. Clean and high quality brake fluid is essential for safety and good brake system performance. You should buy brake fluid with better quality on the market. If the brake fluid is dirty, drain and flush the entire system, then fill the master cylinder with new fluid. Do not reuse the brake fluid. Discard all the released brake fluid.
