A brake rotor is the flat, circular plate that provides your BMW Z3’s disc brake’s friction surface. Your brake pads are squeezed against both sides of the rotor by hydraulic pressure applied to the calipers. The heat generated when you brake is then dissipated by a couple hundred degrees.

This keeps you from dealing with a potentially hazardous condition – overheated brakes. Although some manufacturers say their brake rotors don’t require resurfacing when you change the brake pads, if they are too worn, cracked or seriously warped, you need to replace them too.

(Pedal pulsation in your brakes is a good sign that they are badly warped and need to go.)
