What Causes the Noise After Installing New Brake Pads on a Car?
1 Answers
There are several main reasons why newly replaced brake pads may produce abnormal noises: 1. The noise could be caused by excessive tightness between the brake caliper and brake disc during assembly. 2. Failure to resurface the old brake disc when installing new brake pads may result in improper fitting. This causes the new pads to directly rub against the uneven surface of the old disc, eventually leading to uneven wear on the new brake pads. 3. Defects in the braking system itself. This may cause the brake pads to only partially contact the brake disc, increasing the pressure per unit area and resulting in noise. It is recommended to inspect components such as the caliper and guide pins. 4. Harder brake pad materials are more prone to causing such noises. In contrast, softer brake pad materials tend to produce sharper sounds. Consider replacing them with higher-quality brake pad materials.
