Why Does a New Car's Brakes Make Noise at Low Speeds?
1 Answers
Here are the reasons why a new car's brakes may make noise at low speeds: 1. Human factors after replacing the original brake pads. It may be that the mechanic installed the brake pads incorrectly, and upon removal, you can see that only part of the brake pad surface shows signs of friction. 2. Product factors such as the material of the brake pads. 3. Noise caused by damage to the brake disc. 4. Noise caused by debris or detachment of the friction material. Prolonged braking can easily lead to debris or detachment; if the brake caliper does not retract for a long time, it can cause the brake pads to overheat, leading to the friction material burning out or the adhesive failing, resulting in noise. 5. Rust on the brake caliper. If the brake fluid is not replaced for a long time, the fluid quality deteriorates, and the water in the fluid reacts with the caliper (cast iron), causing rust and resulting in friction noise. 6. The handbrake cable is not functioning properly. 7. Slow return of the master brake cylinder or abnormal return of the brake caliper can also cause brake pad noise.
