What Causes the Clicking Sound When Braking in a Lynk & Co?

The reasons for the clicking sound when braking in a Lynk & Co are as follows: 1. Foreign objects adhering to the brake disc: Fine sand brought by water adheres to the brake disc, or in humid weather or large temperature differences between day and night, condensation or rust forms on the brake disc after rain, acting like tiny particles. Car brake pads come in hard and soft varieties. Hard pads are more wear-resistant, but if there are tiny particles between the hard pad and the gray cast iron brake disc, it can cause a sharp noise and a clicking sound when braking. 2. Missing screws: Loose or damaged screws fixing the brake disc can also cause abnormal brake noise. 3. Brake system malfunction: If the brake system malfunctions, it is necessary to visit a 4S shop or repair shop for inspection and repair.
