Why does my car make a noise when braking?
When the brake pads are too worn, the calipers can grind against the rotor and damage it. Your rotor becomes warped or distorted and so, when you hit the brake, you can feel brake thumping or on-off contact. If your brake parts are undersize, the pads or caliper can move around, making an annoying brake rattling noise.
