What Causes Brake Friction Noise?
1 Answers
The causes of brake friction noise are as follows: 1. Rusty brake calipers: If the brake fluid is not replaced for a long time, it will deteriorate, and the moisture in the fluid can cause the calipers to rust, leading to friction and abnormal noise. 2. Slow return of the master cylinder: Abnormal return of the brake calipers can also cause noise from the brake pads. 3. Foreign objects between the brake pads and rotors: While driving, foreign objects like sand or gravel can get lodged between the brake pads and rotors, creating noise during braking. 4. Hard brake pad material: Most factory brake pads are made from semi-metallic materials, which can easily produce noise when rubbing against the rotors. 5. Improper installation of the brake system: During installation, if the spacing between the brake pads and rotors or the tightness of the nuts is not properly adjusted, it can lead to noise.
