What Causes the Abnormal Noise from the Gap Between Brake Pads and Calipers?

[DeLola]

Here are the specific reasons for the abnormal noise from the gap between brake pads and calipers in cars: 1. Improper installation of brake pads: When installing new brake pads, the old brake discs were not resurfaced, resulting in a poor fit. Poor installation or failing to resurface the old discs before installing new brake pads will cause the new pads to directly rub against the uneven surface of the old discs, eventually leading to uneven wear on the new brake pads. 2. Brake system malfunction: There may be inherent defects in the brake system, causing the brake pads to only partially contact the brake discs. This increases the pressure per unit area during braking, resulting in abnormal noise. It is recommended to inspect components such as the calipers and guide pins. 3. Presence of foreign objects: Foreign objects cause a mismatch in the contact surface, leading to abnormal noise.
