When did the car first change its brake pads(2)
Generally speaking, the brake pads are FF grade, and the friction system is 0.35-0.45. Under the environment of non special vehicles, the service life of the brake pads can reach 60000-100000 kilometers. However, most of the factors affecting the brake pads depend on the daily driving habits. For example, some car owners accelerate and decelerate quickly, often brake hard, and the daily road conditions are complex. Under the environment of steep slopes, the service life of the brake pads may be greatly affected and need to be replaced in advance.
Question 5. What are the reasons for the abnormal brake noise?
1. Most of the abnormal noise of the brake comes from the brake pads, which may be due to the aging of the brake pad surface or being worn very sharp. At this time, it will make abnormal noise, which can be solved by replacing the brake pads;
2. When parking for a long time, the surface of the brake pad is dry and unsmooth, especially in winter, when the weather is wet, the surface of the brake pad appears oxidation and slight rust. At this time, after the vehicle is driven, the first three or four times of stepping on the brake will make abnormal noise, and then it will return to normal;
3. There are foreign matters on the surface of brake pads and brake discs. At this time, the braking may be accompanied by vibration and abnormal noise. If the braking effect is abnormal, get off the vehicle in time for inspection. If there is no abnormal condition, step on it for several times and then it can return to normal;
4. The brake pad is worn to the extreme warning position, and there is abnormal noise. Some are also due to the material problems of the brake pad itself, such as the material is hardened by the weather or there are coarse particles in the material, which will also make abnormal noise.
Question 6. How to maintain the brake system?
1. In daily driving, for manual transmission vehicles, always remember to put down the hand brake. When driving, driving with the hand brake is fatal to the wear of the brake pads. When it is not necessary, do not often brake hard.
2. For automatic models, if it is an electronic handbrake, it is better to remember to release it manually when driving. Although the fuel filler door of many models can release the electronic handbrake automatically now, we obviously feel that the brake has a feeling of being broken. In this case, the wear of the brake pads will also be increased.
3. The car is afraid to stop if it is not afraid to drive, so when parking for a long time, remember to pay more attention to maintenance.
