conventional automotive brake rotors are cast from G3000 grey cast iron. These work well with a pad material designed to operate using adherent friction. Most of the European system rotors are cast from a high carbon G4000 grey cast iron. These work well with a pad designed to operate using abrasive friction, such that the rotor is sacrificial just like the pad.
The brake rotor is a metal disc that is mounted to the hub of each equipped wheel. When the brakes are applied, the brake pads are forced against the brake rotor. If they are not, metal-to-metal contact will occur between the brake rotor and the worn brake pad. 2  This will damage the rotor, which will then need to be resurfaced or replaced. 3  Many brake rotors are not designed to be resurfaced; they should be replaced along with the pads.
