What to Do When There's Abnormal Noise During Low-Speed Braking?
3 Answers
Reasons for abnormal noise during low-speed braking include: 1. Overly worn brake pads: The exposed fixing points of the friction material rub against the brake disc or brake drum, causing abnormal noise. Solution: Replace the brake pads. 2. Poor contact surface: After replacing the brake pads, improper contact with the brake disc or drum leads to point or line contact, resulting in abnormal noise. Solution: Perform a break-in period for the vehicle. 3. Water exposure: Brakes may produce abnormal noise after the car has been through water. Solution: Handle according to water drainage, remove accumulated water, and replace the corresponding parts. 4. Wear: Excessive wear on the brake disc or brake drum. Solution: Replace the brake disc or brake drum.
Last time when I was driving slowly, my brakes suddenly made a squeaking noise, which really startled me. At first, I thought there was some issue, but later I realized it was because the brake pads were severely worn. Initially, I checked myself and noticed some rust on the brake discs. I tried pressing the brakes hard a few times to clear the dust, but the noise didn’t stop. The best solution was to visit a professional repair shop and have them replace the brake pads. Ignoring such a small issue can lead to reduced braking efficiency, especially in traffic jams, where failing to stop in time can be dangerous. I recommend having the technician check the brake pad thickness during regular maintenance, rather than waiting until a problem arises like I did. Additionally, rust is more common in humid weather, so paying attention to any unusual sounds before driving can help prevent issues. Simple steps: clean them yourself first, if that doesn’t work, get them repaired—don’t hesitate to spend the money.
As someone who has worked in a repair shop, I've seen many such cases. Strange noises during low-speed braking usually indicate that the brake pads are nearly worn out or that debris has gotten in. You should immediately check the brake disc surface for scratches; if it's just dust buildup, try a few hard brakes to clear it. If that doesn't work, replacing the pads is crucial, otherwise, it could damage the entire system. I also remind friends not to use low-quality parts, as good brands can extend the lifespan. Don't forget to check if the brake fluid is sufficient, as aged fluid can indirectly cause issues. In daily driving, avoid prolonged braking to prevent overheating. Safety-wise, delaying repairs can lead to brake failure—I've witnessed accidents firsthand. Taking the time to have a mechanic diagnose the issue can save you from major trouble.
