If brakes on a vehicle make any type of noise under driving and braking conditions, it is the sign of a malfunction. Noises may be a variety of brake and brake mounting systems failures, or they may be other problems that occur when the motion of braking creates movement in another part. This can include steering parts, motor mounts and transmission mounts.


Brakes may make a scraping sound at low speeds, which can start quietly in a rhythm coinciding with the speed of the car and gradually become much louder. The scraping rhythm will increase in speed as the car speeds up and then becomes inaudible at higher speeds. This can be a sign of brake shoes or pads that are entirely worn down to the metal, and in this case, the brakes may not stop your car when it involves metal-to-metal braking. Check pads and shoes for wear and replace them if necessary. Wheel bearings that are loose or have failed will also cause this sound; they’ll need repacking or replacement.
