What Causes the Rear Wheel Noise When Releasing the Handbrake to Start?
1 Answers
Introduction to the causes of the noise is as follows: 1. Releasing the brake too slowly when starting: This is a common issue for many automatic transmission car owners. When the brake pedal is released slowly, the engine already has sufficient power to drive the car forward, but the brake is not fully released, causing the moving wheels to be held back by the brake system, resulting in noise. The solution is to release the brake quickly. 2. The brake disc and brake pads sticking together due to rust: This usually occurs after driving in the rain and then leaving the car unused for several days. The brake disc and brake pads rust and stick together, causing noise when starting the car again. The solution is to apply butter or special lubricating oil at the connection between the brake pads and the brake caliper at a repair shop. 3. Metal particle friction noise: Many brake pads nowadays are made of semi-metallic materials, containing a large number of metal fibers. Sometimes metal particles form, producing a sharp noise when pressing or releasing the brake. This noise usually disappears after driving for a while. If it persists, it may indicate poor manufacturing quality, and it is recommended to replace the brake pads promptly to avoid damaging the brake disc.
