I believe that everyone knows that it is a very important part of a car, and it is an indispensable part in a car. The quality of the brake pad is related to traffic safety. If the brake pad is damaged, it needs to be replaced in time. Today, I will introduce to you: What are the main causes of brake pad damage to the disc?

What are the main causes of brake pad damage to the disc?

1. Problems with raw materials

The mineral fiber slag ball in the brake pad will scratch the brake disc, and the slag ball in the mineral fiber is more prone to noise. The material that easily scratches the disc in the raw material is artificial graphite. The artificial graphite itself is very soft, and the impurity silicon carbide is close to diamond. , Enough to scratch the brake disc.

For the artificial graphite used in brake pads, most of the small factories use recycled waste graphite. Large brand products will not use recycled graphite. Some industries have no effect on the silicon carbide in graphite, but when used in brake pads, carbonization Silicon becomes a very harmful substance.

If there is a problem with the raw material of the brake pad, there should be a problem in the same batch, and the possible scope will be wider. In this situation, the brake pads must be replaced in time. If the brake disc is severely damaged, the brake disc must be replaced.

2. Brake pad accessories will also mark the brake pads out of grooves

Some brake pads have alarms, and the alarms are generally made of stainless steel. When the brake pads are worn to the position of the alarm pads, the alarm pads will rub against the brake discs when braking, and a harsh scream will be issued to remind the owner to replace the brake pads.

If the car owner does not care about the noise and allows the alarm pads and brake pads to wear, the brake discs will be scratched. This kind of pit usually only has one groove. If it is not serious, just change the brake pad. When this happens, the position of the groove in the brake disc is generally fixed, which is the position in contact with the alarm pad.

3. Installation problems caused the brake disc to be gnawed

If the brake pads are installed unevenly, causing one or all of them to be in contact with the brake pads for a long time, it will cause the brake discs and the brake pads to rub at high temperature for a long time. In this case, the brake discs are likely to be gnawed, and there will be many groove. This situation can easily occur on the rear brake. When someone is driving, the handbrake is not released, or the handbrake is not placed on the bottom, causing the brake pads to wear for a long time, which is easy to cause.

It can be seen from the brake disc that the disc has changed color under long-term high temperature. If it takes a long time, the brake disc must be replaced. If the brake pads are not installed smoothly, there will be gnawing grooves on the disc surface. And how wide the contact area between the brake pad and the brake disc is, the position of the groove will be as wide as possible. In this case, we cannot rush to replace new brake pads and brake discs, which may continue to cause damage to the brake pads. We should take a good look at where the brake caliper is wrong.
