What Causes the Clicking Sound and Pedal Rebound When Braking Hard?

[VanCaroline]

Causes of clicking sound when braking: 1. Excessive wear of brake discs and brake pads: Both brake discs and pads are high-wear components that experience friction during every brake application. Over time, natural wear occurs, and excessive wear will inevitably lead to abnormal noises, necessitating regular inspection and replacement. Typically, brake pads should be replaced every 60,000-80,000 kilometers, while brake discs require replacement every 100,000-120,000 kilometers. 2. Improper installation of brake pads: If brake pads are installed incorrectly or mismatched in model, abnormal noises may occur. Reinstalling the brake pads can resolve this issue. Vehicle owners should always have brake pads installed at professional auto repair shops, especially those who previously had them replaced at roadside stalls. 3. Other potential causes: Generally, faults in components like calipers, brake discs, or brake pads can generate such noises. If the noise persists, the first step is to check for brake drag. Poor caliper resetting can cause prolonged friction between discs and pads, leading to abnormal noises under certain conditions. Additionally, foreign objects on brake pads or discs may also cause abnormal sounds.
