What Causes the Friction Sound from Brake Discs at Low Speeds?
1 Answers
The reasons for friction sounds from brake discs at low speeds are as follows: 1. Metal hard spots on brake pads: If there are tiny metal particles on the brake pads, they will produce a sharp sound when braking. You can try slamming the brakes a few times or sanding/replacing the brake pads. 2. Severe wear on the brake disc: After prolonged use, deep grooves may form on the brake disc where the brake pads make contact, causing abnormal noises when braking. If the grooves are shallow, sanding the edges of the brake pads may help. If the grooves are deep, replacing the brake disc is necessary. 3. Small stones or a water film between the brake disc and brake pads: If you've driven on gravel roads, in dusty weather, or just washed the car, check for and remove small stones, or press the brakes a few times to wear off the water film.
