What Causes the Clicking Noise When Braking?
2 Answers
The reasons for the clicking noise when braking are: 1. Normal ABS activation, where the vehicle is in a critical lock-up rolling state, causing noise—this is normal; 2. Excessive wear of the brake disc and brake pads; 3. Faulty installation of the brake pads; 4. Brake system malfunction or loose components in the chassis. Solutions for the clicking noise when braking include: 1. Reinstalling the brake pads; 2. Replacing the brake disc; 3. Checking for loose attachments on the brake pads; 4. Inspecting for brake drag or poor caliper retraction; 5. Normal ABS activation—simply apply full force when braking.
I've been driving for ten years and have encountered this kind of brake clunking noise several times. During the last maintenance, it was found that the rear brake pads were almost worn out, and the metal retaining clip was directly scraping against the brake disc. Another time, a friend's car had aged and cracked lower arm bushings, causing a clunking sound when going over speed bumps. Actually, the most concerning with such noises is if the suspension system's ball joints are loose or the shock absorber mounting bolts are loose, especially when encountering bumps at high speeds, which is particularly dangerous. It's advisable not to delay and to quickly go to a repair shop to have the car lifted for inspection. The technician will use a pry bar to shake the components near the tires one by one, making it easy to locate any loose parts. If it's a small part that's broken, it won't cost much to fix. Don't wait until the day the wheel starts to veer off while driving to regret it.
