Why Does the Brake Make Abnormal Noises When Braking?
2 Answers
The reasons for abnormal noises when braking are as follows: 1. Mismatch between the brake pads and brake discs. As long as the vehicle does not deviate during braking, it can be driven normally. 2. There are foreign objects between the brake disc and brake pads. When stepping on the brake, it makes a noise, but pressing the brake firmly a few times will make the noise disappear. 3. The brake pads have worn to their limit. Brake pads are consumables with a certain thickness. When they wear down to a certain extent, metal particles can cause abnormal noises when braking, serving as a reminder to replace the brake pads. In such cases, it is essential to replace them as soon as possible. The braking system is crucial for driving safety and should not be ignored.
I've seen a lot of cases where brakes make strange noises, mainly due to issues between the brake pads and discs during friction. If the brake pads wear too thin, the metal material inside will come into contact with the disc, producing a squeaky sound that's quite harsh on the ears. Additionally, if the brake disc is rusty or has uneven surfaces, it can also create odd noises, especially when driving in humid weather or after rain. Dust or small stones stuck in between are even more annoying, causing the brakes to squeal every time you use them. To avoid this, I recommend regularly checking the thickness of the brake pads—generally, you should inspect them around every 30,000 kilometers, and replace them if necessary. New cars might also produce slight noises during the first few drives, which is normal break-in wear; it usually goes away after a few days, so there's no need to worry too much. Safety comes first—if you hear unusual noises, it's best to get them checked at a shop to prevent the problem from worsening and affecting braking distance.
