What Causes Rear Wheel Brake Noise?
2 Answers
Rear wheel brake noise can be attributed to the following reasons: 1. Reason one: When the car's brake pads are severely worn, metal friction noise usually occurs, and the sound can be quite harsh. If this is accompanied by reduced braking effectiveness, then the noise is likely related to this issue. 2. Reason two: The noise could also be caused by incorrect installation of the brake system. If this is the case, it is necessary to seek professional inspection and repair promptly. More details about the brake system are as follows: 1. Detail one: The brake system is crucial for overall driving safety. Once the brake system malfunctions, the consequences can be unpredictable. Within the entire brake system, brake pads play a pivotal role, so timely replacement of brake pads is essential for the safety of the driver. 2. Detail two: Generally, when a car's total mileage reaches 30,000-40,000 kilometers, the brake pads need to be replaced. When the mileage reaches 70,000 kilometers, the car's brake discs should be replaced.
I've encountered the issue of rear brake squealing several times while driving, which is actually quite common. The first time it happened, I thought it was due to the road surface, but then the noise became more frequent, especially when braking, producing that sharp screeching sound. I asked an experienced driver about it, and he told me the possible causes could be multifaceted: the most common one is uneven or excessively worn brake pads, which cause the metal to scrape against the disk and make noise; or it could be due to dust or small stones stuck between the brake pads and disk, especially after driving on muddy roads in rainy weather, which can lead to debris buildup; another possibility is rust or deformation of the brake disk itself, causing an uneven surface that results in noise when friction occurs. Additionally, loose brake calipers or insufficient brake fluid could also trigger this sound. I think the most important thing is not to ignore it—once you notice it, you should address it promptly. In my case, I drove to a repair shop, replaced the brake pads, and cleaned the system, and the noise was significantly reduced. Regularly checking the rear brake components during maintenance can effectively prevent this issue—after all, safety comes first.
