What Causes the Clicking Sound After Replacing Brake Discs?
2 Answers
Replacing brake discs and then hearing a clicking sound is due to the break-in period required between the brake pads and the new brake discs. After the break-in period, it should return to normal: Some brake pads contain metal wires or other hard material particles that are relatively large. When the brake pads wear down to these materials, they may produce noise when in contact with the brake discs. Once these materials are worn away, the noise should stop. This is normal and does not affect safety, though the noise can be annoying. If the sound is truly unacceptable, you can replace the brake pads with higher-quality ones to resolve the issue. Tips to Extend Brake Pad Lifespan: Avoid sudden braking: Emergency braking can significantly damage brake pads. When driving normally, try to brake gradually or use the 'pump brake' method to minimize wear on the brake pads.
As a seasoned driver with over 20 years of experience, I've seen many cases where the brakes make a clicking sound after replacing the rotors. The most common reason is burrs or uneven surfaces on new brake rotors, which cause friction noise during the initial break-in period with the brake pads. This usually disappears after driving a few hundred kilometers. Another possible cause is improper installation, such as loose screws or not tightening them to the specified torque, which can result in a clicking sound while driving. It could also be due to dirt, metal shavings, or other debris stuck on the brake pads. Once, a friend's car had this issue—he thought it was serious, but a simple cleaning fixed it. My advice is to first check the installation details and drive for a few days to see if the noise persists. If it continues, take it to a professional shop immediately to avoid potential caliper issues that could affect braking performance—safety first! In short, don’t worry too much; most of the time, it's a minor issue, especially common during the break-in period.
