What are the reasons for abnormal noises after replacing brake discs and pads?
1 Answers
The reasons for abnormal noises from newly replaced brake pads are as follows: 1. The most likely cause is an improper contact surface, where the old brake disc was not resurfaced when installing new brake pads, resulting in a poor fit. If the installation is improper or new pads are installed without resurfacing the old disc, the new pads will directly rub against the uneven surface of the old disc, ultimately causing uneven wear on the new brake pads. 2. Another possible reason is a defect in the brake system itself, causing the brake pads to only partially contact the brake disc. This increases the pressure per unit area during braking, leading to abnormal noises. It is recommended to inspect components such as the caliper and guide pins.
