What are the causes of abnormal brake noise while driving?
1 Answers
The causes of abnormal brake noise while driving are: 1. Improper installation of brake pads causing abnormal friction; 2. Hard objects such as sand, gravel, or metal fragments stuck in the brake pads; 3. Inconsistent size of the friction blocks in the brake pads or severe wear of the brake pads; 4. Insufficient break-in period for the brake pads. The materials used for brake pads include: 1. Asbestos, cellulose, sintered glass; 2. Carbon fiber friction materials; 3. Powder metallurgy friction materials; 4. Semi-metallic friction materials. The method for replacing brake pads is as follows: 1. Open the engine compartment to check the brake fluid level to prevent overflow during replacement; 2. Remove the wheel where the brake is located; 3. Remove the bolts of the brake caliper and take out the brake pads; 4. Install new brake pads, tighten the guide bolts, and complete the replacement.
