Why Does the Brake Make Noise at Low Speed?
1 Answers
The reasons for brake noise at low speed are: 1. The new car is in the break-in period; 2. Malfunction of the caliper, brake disc, or brake pads; 3. Severe wear of the brake pads. If the noise is continuous, the first thing to check is whether there is any dragging brake. Poor caliper reset can cause prolonged friction between the disc and the pads, which may produce abnormal noise under certain conditions. If the noise occurs immediately after installing new brake pads, it may be due to a size mismatch between the new brake pads and the friction blocks. Braking is achieved through intense friction between the brake pads and the brake drum. When driving in water, the wheels are almost submerged, leaving a layer of water film between the brake pads and the brake drum, acting like a lubricant. This reduces the friction between the brake pads and the brake drum, making it difficult to control the car's stopping. Additionally, water inside the drum is not easily dispersed. This brake failure phenomenon occurs very quickly. After leaving the water, driving while applying the brakes several times will wipe away the water droplets between the brake pads and the brake drum. The heat generated by friction will also dry them, allowing the brakes to quickly regain their original sensitivity.
