What Causes the Noise When Braking?
2 Answers
There are several main reasons for noise when braking: 1. Excessive wear of the car's brake discs and brake pads. 2. Insufficient lubrication between the friction pads. 3. Issues with the installation of the brake pads, such as incorrect model or reversed installation. Additional Information: 1. The braking performance of a car depends on the brake pads, which generally consist of a steel plate connecting the heat insulation layer and the friction block. The heat insulation layer is made of non-heat-conductive materials, while the friction block is mainly composed of friction materials and adhesives. 2. Since brake pads frequently undergo friction, they are consumable items for cars. Lower-quality brake pads wear out faster and require more frequent replacement, so it is essential to choose high-quality brake pads. The car's braking system is a crucial part of ensuring safe driving, as it allows for emergency braking and prevents accidents like rear-end collisions.
A few days ago, I encountered a similar situation while driving to work. The squeaking noise when braking was so annoying that I thought there was a serious problem with the car. I immediately drove to a repair shop run by my friend. The mechanic checked it and said the brake pads were worn too thin, and the metal backing plate was scraping against the brake disc, causing the noise. It could also be due to dust or small stones stuck in the brake disc, creating loud friction. That's when I remembered I didn't clean the brakes properly during the last maintenance. I'll have to pay more attention in the future. I suggest you first try gently pressing the brake to listen to the sound. If it's a regular noise, it means the pads need replacing. Alternatively, find an empty space and repeatedly brake at low speed a few times—it might clear any debris. If that doesn't work, go to a professional shop for a thorough check. Don't risk driving around, as the braking system is a matter of life and death!
