What Are the Reasons for Abnormal Noises When Braking Too Hard?
1 Answers
There are several reasons for abnormal noises when braking too hard, including the brake being in the break-in period, normal activation of the ABS system, metal hard spots on the brake pads, and severe wear of the brake disc. Brake in the break-in period: New cars or recently replaced brake discs and pads will have a break-in period, during which some abnormal noises are unavoidable. The noise will disappear after using the brakes a few times. Normal activation of the ABS system: During emergency braking, the brake pedal may produce continuous abnormal noises, sometimes accompanied by a kicking sensation, indicating that the ABS system is activated, which is a normal sound. Metal hard spots on the brake pads: There may be some tiny metal particles inside the brake pads, which can produce sharp, piercing sounds when lightly braking. Solutions include forcefully applying the brakes several times, removing and re-grinding the brake pads, or replacing them with higher-quality ones. Severe wear of the brake disc: Severe wear on the brake disc can form deep grooves around its circumference, causing friction between the brake pads and the edges of the grooves, resulting in abnormal noises. The solution is to promptly inspect the brake disc and replace it if the wear is severe.
