Why is there a creaking sound when releasing the brake?
1 Answers
Reasons for creaking sound when releasing the brake: 1. False fault: When slowly releasing the brake pedal, the engine already has sufficient power to drive the car forward, but the brake is not completely released. The moving wheels being held by the brake system will naturally produce abnormal sounds; 2. Genuine fault: The brake disc and brake pads stick together due to rust, causing abnormal sounds. Many brake pads nowadays use semi-metallic materials containing a large number of metal fibers. Sometimes metal particles may form, producing harsh sounds when applying or releasing the brakes. This condition usually disappears after driving for a while. If it persists, it may indicate poor manufacturing quality, and it is recommended that the owner replace the brake pads in time to avoid scratching the brake disc.
