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.
Drum brake. A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a clasp brake.
