What to Do When There's Abnormal Noise During Low-Speed Braking?
2 Answers
Reasons for abnormal noise during low-speed braking include excessive wear of brake pads, improper contact surface, water exposure, and wear. Specific explanations are as follows: Excessive wear of brake pads: Leads to the exposure of friction material fixing points, causing friction with the brake disc or brake drum and resulting in abnormal noise. Solution: Replace the brake pads. Improper contact surface: After replacing the brake pads, if the contact surface with the brake disc or drum does not fit properly, it can form point or line contact, leading to abnormal noise. Solution: Perform a break-in for the vehicle. Water exposure: Brakes may produce abnormal noise after the car has been exposed to water. Solution: Handle according to the water drainage situation, remove accumulated water, and replace the corresponding parts. Wear: Excessive wear of the brake disc or brake drum. Solution: Replace the brake disc or brake drum.
Recently, there's been some strange noise when braking at low speeds, which has been making me quite anxious. I've been driving for five years and have encountered similar issues several times. Usually, it's caused by severely worn brake pads or small stones stuck between the brake discs. Last time, I tried cleaning the wheel hubs myself and sprayed some rust remover, which helped a bit. But for safety's sake, I still went to the repair shop immediately. The mechanic found that the brake pads were almost worn out and reminded me to check them every 10,000 kilometers. Otherwise, low-speed noise could indicate a risk of brake failure at high speeds. Now, I've developed a habit of using a flashlight to quickly check the brake condition every month, especially after rainy or humid weather. Anyway, don't skimp or be lazy—fix what needs fixing. Safety comes first when driving.
