Brake pads in automobiles are also called brake pads. Brake pads are an important part indispensable in the driving of a car. In the brake system, a common fault is that the brake pads will make abnormal noises, but many people don’t know it. How does this kind of abnormal noise cause it, let me introduce to you what causes the abnormal noise of the brake pads?

What causes the abnormal noise of the brake pads?

1. The reason for the abnormal noise of the brake pads may be that some small particles such as small stones enter between the brake pads and the brake discs during the driving of the vehicle, causing the brake pads to make a noise. In this case, , No need to repair, just run more.

2. When the brake pads are just installed, the friction surfaces between them are not exactly the same, so each brake is a process of mutual torture and trial, which will cause abnormal noise of the brake pads.

3. If the fixing screw of the brake disc is lost or damaged, it will also cause abnormal noise from the brake. This frequency sounds sharp. When the vibration frequency of the brake disc and the brake pads are the same, they will resonate and make a sharp and harsh sound.

4. The service life of brake pads is also limited. Generally speaking, they should be replaced once every 60,000 kilometers. When the brake pad reaches the warning line or is excessively worn, it will often produce some abnormal noises, which are mainly manifested as metal friction sound, but also have performances such as poor braking effect.

5. Sometimes, if the material of the brake pad is too hard, there will be abnormal noise, because many original brake pads are generally made of semi-metallic material, so it is easy to produce noise when rubbing with the brake pad.
