Talk about why the car brake pad brake when there is a clump clump sound

In the Porsche, it is particularly obvious that the car’s brake pads will have an abnormal thumping sound when moving forward or reversing at low speeds, but it has no effect on braking performance. There are three aspects to this phenomenon.

There are generally three reasons for abnormal braking noise. One is the material problem of brake pads. Most of the brake pads used now are semi-metal brake pads, and the metal in the brake pads will produce abnormal noise when braking.

Brake pad brand manufacturers solution: Replace the brake with a large coefficient of friction products.

There is also a problem is that the brake disc is not uniform, the brake disc in the process of use, the middle may have an uneven brake disc, when the brake disc is not uniform, it is easier to make an abnormal sound when stepping on the brake, especially the replacement of the so-called “original brake pad” the middle brake disc will be raised, shaking up and down, and the impact sound when stepping on the brake.

The solution of the automobile brake pad manufacturer: replace the brake disc or smooth the brake disc (the brake disc is not recommended for heavy vehicles).

Another reason is that the edges of the brake disc bulge due to natural wear. When we replace the new brake pads, there will be abnormal noise because the brake pads and the brake disc can not be fully fitted to the brake.

Solution: When replacing the new film, chamfer or replace the brake disc.
