Grinding, pulsating and a lack of stopping power are signs of a bad brake rotor. If your brake pads have worn deep into your rotor, the lip on the outer edge of the rotor can cut into your pad wear sensors, causing a brake pad warning to appear in the instrument cluster - even if your brake pads are new. Rotors should be checked every time you service your brakes.

These rotors are specially coated for corrosion resistance.
