The brake pad is the brake pad. In the automobile braking system, the brake pad is the most critical safety part. The brake pad plays a decisive role in all braking effects, so the good brake pad is the protection god of people and cars. Generally speaking, a pair of brake pads can be used for 100000 kilometers without any problem. They can be used well, even up to 150000 kilometers. Let's look at the maintenance methods of brake pads.
1. Generally, the first replacement can be carried out between 60000 and 70000 kilometers. It is not only necessary to check the remaining thickness, but also to check the wear status of the shoe, whether the wear degree of both sides is the same, and whether the return is free. If abnormal conditions are found, they must be handled immediately.
2. The brake disc is generally composed of iron lining plate and friction material. Do not replace the shoe until the friction material is worn out. Once the wear limit is reached, the instrument will give an alarm and prompt to replace the shoe. The shoes that have reached the service limit must be replaced. Even if they can still be used for a period of time, the braking effect will be reduced and the driving safety will be affected.
3. It is recommended that you do not change the brand of the original brake pad at will when you need to change the brake disc. It is better to choose the specification of the original configuration. Only then can the braking effect between the brake pad and the brake disc be the best and the wear be the least.
4. When replacing the shoe, use special tools to drive the brake wheel cylinder back. It is not allowed to press back with other crowbars, which will easily lead to the bending of the brake caliper guide screw and the brake pad jamming.
5. After the replacement, be sure to step on the brake several feet to eliminate the gap between the shoe and the brake disc, causing the first foot to fail to brake, which is prone to accidents.
6. After replacing the brake disc, it must go through a period of running-in. You can pull the car to the high speed and run, but you should keep the speed, not too fast.
The brake pad is the most critical safety part in the brake system of the automobile. Because the brake pad plays a decisive role in the brake effect, the good brake pad is the protector of people and cars. After the friction material is used, the brake pad should be replaced in time, otherwise the steel plate and the brake disc will contact directly, and eventually the brake effect will be lost and the brake disc will be damaged.
