Abstract

Frictional pairing in motor vehicles, including a carbon-ceramic brake disk or a grey cast iron brake disk and a brake pad for the brake caliper of the parking brake, characterised in that the brake pad comprises a fiber-reinforced ceramic composite material, which has a matrix with phases of silicon carbide and reinforcement fibers of carbon, graphite, silicon carbide or whiskers of high-melting metals with a melting temperature of over 1500° C., and a parking brake comprising these material.
