What Causes Abnormal Noise When Braking in a Car?

[LaIris]

Car braking with abnormal noise can be caused by the following reasons: 1. Excessive wear of brake discs and brake pads. Both brake discs and brake pads are high-wear components that experience friction every time the brakes are applied. Over time, they naturally wear out, and when excessively worn, abnormal noises can occur. Therefore, regular inspection and replacement are necessary. Typically, brake pads should be replaced every 60,000-80,000 kilometers, while brake discs should be replaced every 100,000-120,000 kilometers. 2. Improper installation of brake pads. If the brake pads are installed incorrectly or the model does not match, abnormal noises may also occur. In such cases, the brake pads should be reinstalled. It is advisable to have this done at a professional auto repair shop. 3. Normal activation of ABS. The ABS system operates by repeatedly engaging and disengaging the brakes, keeping the vehicle in a state of near-lockup. When the brakes are applied sharply, causing the ABS to activate, a clicking sound may occur, which is a normal phenomenon.
