What Causes the Clicking Sound When Braking at Low Speeds?
1 Answers
Low-speed braking noise is a normal activation of ABS. The working process of ABS is essentially a cyclic process of locking and releasing, keeping the vehicle in a state of near-lock rolling. Therefore, when ABS is triggered by hard braking, it produces a clicking sound, which is normal. In such cases, simply press the brake pedal firmly to the floor. For automatic transmission vehicles, the clicking sound when braking may primarily be due to the electronic linkage between the braking system and the automatic transmission. Specific reasons include: Excessive wear of brake discs and pads: Both brake discs and pads are high-wear components, subjected to friction with each brake application. Over time, wear occurs naturally, and when excessive, it can lead to abnormal noises. Regular inspection and replacement are essential. Typically, brake pads should be replaced every 60,000-80,000 kilometers, while brake discs last about 100,000-120,000 kilometers. Improper installation of brake pads: If brake pads are installed incorrectly or mismatched in type, abnormal noises may occur. Reinstallation may be necessary. It is advisable to have brake pads installed at professional auto repair shops, especially for owners who have had them replaced at roadside stalls. Other possible causes: Faults in the caliper, brake disc, or brake pads can also produce such noises. If the noise persists, first check for dragging brakes. Poor caliper reset can cause prolonged friction between the disc and pad, leading to abnormal noises under certain conditions. Additionally, foreign objects on the brake pads or discs can also cause noise.
