What are the causes of brake pad noise?
1 Answers
There are several reasons for brake pad noise: 1. The brake pads emit a sharp, screeching sound. This piercing noise is caused by the fault alarm piece of the brake pad, which may indicate that the brake pads are worn out or there are foreign objects on them. Solution: When encountering a screeching sound from the brake pads, the first step is to check whether the brake pads are worn out or if there are any foreign objects. If the brake pads are worn out, they should be replaced immediately. If there are foreign objects, remove the brake pads, take out the foreign objects, and reinstall them. 2. If the sound is a dull noise, it is mostly due to problems with the brake caliper, such as wear on the sliding pins or detachment of the spring plates. Solution: Immediately check the brake caliper for wear on the sliding pins or detachment of the spring plates. If found, replace them immediately. 3. If the sound is a hissing noise, there could be multiple issues, including problems with the caliper, brake disc, or brake pads. If the noise persists, first check for dragging brakes. Poor caliper resetting can cause prolonged friction between the disc and pads, leading to abnormal noise under certain conditions. If the noise occurs right after installing new pads, it may be due to inconsistent dimensions between the new pads and the friction blocks. Solution: First, check the caliper, brake disc, and brake pads for any friction issues. If the noise is from newly replaced brake pads, wait for the new pads and friction blocks to fully break in. 4. If a clattering noise occurs after driving for a while, it may be caused by loose attachments on the brake pads. Solution: Check if the attachments on the brake pads are loose. The best solution is to reinforce them or replace the brake pads with new ones.
