Abstract
A method of protecting an aluminum braking surface is disclosed. A brake lining associated with the surface is formed of a brake lining material which includes as a part of the composition an additive of sodium fluoride or cryolite. When a brake system composed of the braking surface and the brake lining are subjected to repeated braking actions, the additive of the brake lining reacts with a surface layer of the aluminum braking surface to form a tenacious, wear resistant layer thereon. The additive, upon further braking actions serves to maintain the wear resistant layer as fresh aluminum is exposed during normal wear of the braking surface over its useful life.
