A composite brake drum includes an outer component having an outer surface and an inner surface defining an internal cavity. The composite brake drum also includes an inner liner that is mounted within the internal cavity and is attached to the inner surface. The inner liner is made from a metal matrix composite such as silicon carbide aluminum (SiCAl), for example. The outer component is formed from cast iron or stamped steel. The metal matrix composite provides a braking surface that is less corrosive than a braking surface that would be provided by ferrous materials.
