What Causes the Sizzling Sound from the Rear Wheels?
3 Answers
The reasons for the sizzling sound from the rear wheels: 1. Worn brake pads: One possible reason is severely worn brake pads. Thinner brake pads can produce metallic noises during operation, which not only affect driving comfort but also impact the vehicle's braking performance. Therefore, it's necessary to visit a 4S shop for repair or replacement. 2. Debris in the brake disc: Another possible cause is debris, such as small stones or broken nails, entering the brake disc, which can also create abnormal noises while driving. 3. Deformed brake pad shield: If the brake pad shield is deformed, it may rub against the rotating tire during driving, producing abnormal noises. In such cases, promptly visit a repair shop for inspection, repair, or replacement.
I often hear a squealing sound from the rear wheels while driving, especially when turning or braking. I think it might be because the brake pads are almost worn out—when they wear down, the metal backing rubs against the brake disc, producing that harsh noise. It could also be due to a faulty wheel hub bearing; once it rusts or gets damaged, it tends to squeak while rotating. Last time I had it checked, the mechanic said small stones or dust stuck in the tires might also cause such noise. This sound isn’t just annoying—it can also affect driving safety. If you keep driving like this, the braking performance may worsen. So I suggest you visit a reliable repair shop as soon as possible—don’t delay, or the repair cost could get much higher. I dealt with this issue last month, and now my car runs much quieter, which is quite reassuring.
I run an auto repair shop and often hear customers complain about a squeaking sound from the rear wheels. Based on my experience, this is mostly due to issues with the braking system, such as excessively worn brake pads making noise when rubbing against metal. It could also be loose ball joints in the suspension system, causing squeaks during vibrations. Worn wheel bearings are another common issue, especially in older cars—rough bearing balls will create noise. Sometimes, small stones stuck in the tire treads can also produce a squeaking sound with each rotation. It's important to check these issues promptly to avoid complete failure of the tires or brakes. I recommend regular maintenance, with a quick inspection every 5,000 kilometers. You can try cleaning the wheels yourself, but if the noise persists, don’t ignore it—visit a professional shop immediately for diagnosis. Safety comes first. Delaying repairs can double the cost—I’ve seen many cars end up needing major repairs because of this.
