What Causes the Abnormal Noise After Replacing Motorcycle Brake Pads?
2 Answers
Motorcycle abnormal noise after replacing brake pads is usually caused by not grinding the old brake disc when installing new brake pads. Here are the details: Reasons for abnormal noise: Not grinding the old brake disc when installing new brake pads causes improper installation. Improper installation or installing new brake pads without grinding the old disc will cause the new pads to directly rub against the uneven surface of the old disc, ultimately leading to uneven wear of the new brake pads. Solutions for abnormal noise: If there is abnormal noise after replacing the brake pads, it is necessary to go to a 4S shop for inspection. If there is a "metal rubbing against metal" hissing sound when lightly applying the brakes, the reason may be the initial break-in effect of the brake pads after installation. In this case, the brake pads must be replaced immediately.
I just replaced the brake pads on my motorcycle last time, and as soon as I braked, I heard a screeching sound, which made me really anxious. After asking a few friends who are into motorcycles, I realized this is actually quite common. First, new brake pads have a rough surface and haven't been properly bedded in with the brake disc. Just ride a few dozen kilometers and gently brake a few times to solve this. Second, if the screws weren't tightened properly or the pads were misaligned during installation, it could also cause strange friction noises. It's best to check yourself to see if anything is loose. Additionally, if the brake disc is worn with grooves, the new pads will make noise when rubbing against it, and the disc surface might need resurfacing. Lastly, if the brake pad material is faulty or there's dust stuck in them, they might squeak. It's recommended not to brake too hard right after replacement. Ride for a few days to see if the noise persists. If it doesn't stop, go to the shop for adjustments immediately to avoid safety issues.
