How to Deal with Abnormal Noises When Braking?
1 Answers
When abnormal noises occur during vehicle braking, the common causes include the following: 1. New car making noise when braking: The brake pads and rotors of a new car have not yet been fully broken in, which can sometimes result in a "squeaking" friction sound. This is normal, and the noise will naturally disappear after some use. 2. Noise after replacing brake components: After installing new brake pads, incorrect installation may cause abnormal noises. Common installation errors include mounting the brake pads upside down, where the metal side contacts the rotor, leading to noise. 3. Noise due to brake rotor issues: Prolonged use can cause deep grooves on the rotor surface or deep steps at the edges. Uneven contact between the brake pads and rotor can produce noise. In such cases, the rotor needs replacement or resurfacing using a brake lathe. 4. Noise caused by sand or debris in the brakes: If foreign objects like sand or small stones get between the brake pads and rotor while driving, a sharp hissing sound may occur. Continuing to drive normally will usually dislodge the debris, eliminating the noise. If the noise persists, the wheel may need removal to extract the debris. 5. Noise during hard braking: When braking sharply, a clicking sound accompanied by pedal vibration is normal and indicates ABS activation.
