What Causes the Squeaking Noise When Slowly Releasing the Brakes?
2 Answers
There are generally two reasons: one is the friction between the wheel and the braking system, and the other is rust between the brake disc and brake pads, which causes the squeaking noise. Brake Pad Replacement: It is recommended to regularly check the condition of the brake pads on household vehicles. Brake pads tend to wear significantly between 30,000 to 60,000 kilometers and should be replaced. Typically, a brand-new set of brake pads is about 1.5 cm thick. When the thickness of the brake pads is less than 0.5 cm, replacement is necessary. Importance of Brake Pads: Brake pads can be life-saving in critical moments, as they are a crucial component of a car's braking system. The quality of the brake pads determines the effectiveness of the braking performance and directly impacts personal safety, ensuring safe travel.
I've encountered the issue of squeaking noises when slowly releasing the brakes several times. The most common cause is when the brake pads are nearly worn out, causing metal-to-metal contact with the brake discs that produces a squealing sound. In my experience, if the car has been driven for a long time or frequently undergoes hard braking, the brake pads wear thin and start making noise. Another reason could be rust on the brake discs, especially during humid seasons or after prolonged parking, where rust buildup causes scraping sounds during gradual brake release. Don't underestimate these sounds—they're like a warning that it's time to replace your brake pads. Once when driving an older car in mountainous areas, the noise kept getting worse until I discovered the brake pads were paper-thin, nearly causing an accident. My advice is to regularly check your brake condition and visit a repair shop as soon as you hear unusual noises. It's best to replace both the brake pads and discs together to prevent further deterioration that could compromise safety.
