What Causes the Abnormal Noise from Newly Replaced Brake Pads?

[ReaganDella]

Newly replaced brake pads produce abnormal noise due to mismatched contact surfaces, as there is a required break-in period between the new brake pads and the old brake disc. More details about brake pads are as follows: 1. Installation of new brake pads without resurfacing the old brake disc: This leads to improper fitting. If the installation is mismatched or new pads are installed without resurfacing the old disc, the new pads will directly rub against the uneven surface of the old disc, eventually causing uneven wear on the new brake pads. 2. Material issues with the brake pads: If non-genuine brake pads are used, the larger particles in the pad material can easily generate noise during braking. 3. Installation problems: Lack of lubricating paste (also known as noise reduction paste) or improperly installed brake pad shims. In such cases, reinstalling the brake pads properly should resolve the issue.
