Why Does the Car Make Noise When Braking?
2 Answers
There are several main reasons why a car makes noise when braking: 1. Normal ABS activation: The ABS operation process is actually a cyclic process of locking and releasing, keeping the vehicle in a state of near-lock rolling. When the ABS is activated by sudden braking, noise may occur. 2. Rust on brake pads/discs: After prolonged parking, especially in humid weather or after rain, this issue can usually be resolved by driving for a while. 3. New brake pads: New cars or newly replaced brake pads may produce similar noises, as the new brake pads and discs require a break-in period. When braking, such noise may occur.
My recent car also made strange noises when braking. I didn’t pay attention at first, but when the sound grew louder, I took it to the repair shop. The mechanic said the brake pads were worn thin and small stones were stuck in them. Cleaning didn’t help, so I had to replace them. He said this is the most common issue, especially after long drives or when the brake discs rust after rain—the squeaking is a warning of metal friction. The lesson I learned is not to delay: regularly check the brake pad thickness to ensure safety. Pay attention to road conditions and avoid sudden braking to extend their lifespan. It’s best to service and inspect the braking system every six months to avoid issues on the road. If the noise gets really bad, go straight to a professional shop—saving money isn’t worth risking your life.
