What Causes the Clicking Sound When Starting and Braking?

[LaAubree]

There are three possible reasons for a clicking sound when starting and braking: 1. Excessive wear on the brake disc and brake pads. The edge of the brake disc may develop a raised area due to wear, causing noise when new brake pads cannot fully align with the disc during braking. Brake discs and pads are high-wear components, as they constantly rub against each other during braking. When excessively worn, they produce noise and require regular maintenance and replacement. 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. Incorrect installation or mismatched brake pad models can also cause noise. Most brake pads are made of semi-metallic or semi-asbestos materials. If the metal in the pads is too hard, it may generate noise during braking. 3. Faults in the caliper, brake disc, or brake pads can also produce this sound. If the noise persists, first check for dragging brakes. Poor caliper retraction can cause prolonged friction between the disc and pad, leading to noise under certain conditions. Additionally, foreign objects on the brake pads or discs can also cause abnormal sounds.
