Abstract

A brake unit including a brake disc of a material having a high thermal loading capacity and a brake pad that cooperates with it in tribological fashion. The brake disc is essentially made of a short-fiber reinforced ceramic material, whose thermal conductivity, in particular transversely to the disc surface, is at least 20 W/mK, preferably about 30 to 45 W/mK. The brake disc is combined with a brake pad having an organically bonded matrix. The brake pad may be a conventional series brake pad. The brake unit provides an optimal pairing of a brake disc, having a high thermal loading capacity, with a conventional brake pad in light of a reasonably expected brake pad service life, and in light of other tribological requirements, such as the friction coefficient.
