Question: Bmw Brake Noise When Stopping?

These sounds mean that your brake pads have completely worn down and the calipers are rubbing against the rotors. This is normal when heat causes your brake pads to expand. However, most BMW brakes come with anti-rattle clips to keep you from hearing this sound.

Why do my brakes make a noise when I stop?

If the noise pops up just before your vehicle comes to a complete stop, as opposed to squealing throughout the entire range of braking, the cause could be a brake pad that is vibrating against the rotor. A set of brake pad vibration damper pads could cure the squeal, but there’s no guarantee.
