What Causes Abnormal Noise During Low-Speed Braking in Cars?

[OAdalynn]

Abnormal noise during low-speed braking in cars can be attributed to the following reasons: 1. The vehicle is in the break-in period; 2. Malfunctions in the caliper, brake disc, or brake pads causing abnormal noise; 3. Severe wear of the brake pads can also lead to abnormal noise during low-speed braking. If the noise persists, the first step is to check for any dragging brakes, as poor caliper resetting can cause prolonged friction of the disc, resulting in abnormal noise under certain conditions. If the noise occurs immediately after installing new brake pads, it indicates that the new pads and friction blocks are of inconsistent sizes, causing the noise. For new vehicles in the break-in period, such noise is normal as new brake pads and discs require a break-in process. When braking, if the hard spots on the brake pads are encountered, this type of noise may occur. Additionally, the presence of sand, gravel, or other debris on the brake pads or discs can also produce such noises.
