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.
How to Replace Brake Rotors. Brake rotors are metal discs that are attached to the axles of a vehicle. When the driver pushes the brake pedal, the brake pads press on the rotor, creating friction, which forces the wheels to turn slower. That friction also causes the disc to wear out, and to need resurfacing (turned). But, the brake rotors may need to be replaced due to damage or excessive wear below a specified limit, how soon depending on miles driven and driving conditions (heat, dirt, sand, rocks, road salt, etc.).
