What Causes the Clicking Sound When Pressing the Brake?
2 Answers
The reasons for the clicking sound when pressing the brake: 1. It could be the activation of the ABS anti-lock braking system. When the ABS system activates, in addition to the clicking sound, the brake pedal may also kick back, and during the braking phase, the brake pedal may slightly or slowly descend. 2. The noise could be caused by the brake pads and brake discs, with excessive wear being a common reason. 3. Foreign objects on the brake pads or brake discs could also lead to abnormal noises. Solutions: 1. If the noise is due to excessive wear, the solution is to directly replace the brake pads and brake discs. 2. If the problem cannot be identified, it is recommended to visit a 4S store or a professional auto repair shop for an initial inspection to determine the issue and proceed with targeted repairs.
I've dealt with similar issues before, and there are quite a few reasons why a car makes a clunking sound when braking. If the brake pads are worn too thin or the metal backing plate is exposed, they can produce abnormal noises during friction. Uneven or rusted brake disc surfaces may also cause a clunking sound when starting to move. Additionally, if the brake caliper pins lack lubrication or are rusty, they can make a creaking noise when pressed, especially common in humid weather. Loose or deformed brake shields rubbing against the discs can also cause clunking. I recommend first checking if the brake pad thickness is less than 3 millimeters or manually shaking the brake shield to see if it's secure. I've seen several cases where car owners ignored such sounds, resulting in premature brake disc failure and unnecessary expenses. Safety comes first—if possible, get it checked at a repair shop as soon as you can.
