What Causes Brake Noise While Driving?
2 Answers
The causes of brake noise while driving are: 1. Metal particles or small gravel between the brake pads and brake discs; 2. Excessive wear of the brake discs or brake drums; 3. Overly hard brake pads; 4. Rust on the brake calipers; 5. Inflexible handbrake cables; 6. Slow return of the master brake cylinder. Solutions for brake noise while driving include: 1. Checking the lubrication of the top rubber or buffer rubber of the shock absorbers for issues; 2. Running in new brake friction pads; 3. Timely replacement of brake pads; 4. Cleaning foreign objects from the surface of the brake discs. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, and other transport tools or machinery.
My car has made squeaking noises several times when braking, and after checking, I found there are several main reasons. The most common one is that the brake pads are worn thin; when the friction material on the metal plate is worn away, the metal directly rubs against the brake disc, producing a sharp sound. Additionally, if the brake disc surface has rust or dirt, especially in humid weather, abnormal noises occur when braking. Foreign objects getting stuck are also common, such as small stones lodged in the gaps between the brake pads, causing noise while driving. If the brake caliper is loose or the spring is misaligned, it can also lead to unstable noises. It's best to stop and inspect yourself first, checking if the brake disc is smooth and free of scratches. If the noise occurs frequently, don’t hesitate—take it to a professional repair shop immediately for inspection and replacement to avoid longer braking distances leading to accidents. Regular maintenance, such as checking brake pad thickness every 5,000 kilometers, can greatly reduce such issues.
