Abstract

A brake unit comprising at least one brake and at least one brake pad having at least one friction lining is described. The brake has a disk brake with a brake rotor made of a ceramic-metal composite (CMC) whose outer surface or surfaces at least partially form a friction surface for the at least one friction lining, and a disk brake cup that is mounted on the disk brake by way of one or more mounting elements. The friction surface of the disk brake has a hardness of approximately 1600 to 2500 HV, and the at least one friction lining has a coefficient of friction of approximately 0.3 to 0.5. The disk brake cup and/or the mounting elements form a corrosion-inhibiting attachment to the disk brake. The brake unit can be operated in corrosion-free fashion over a service life of at least approximately eight to 10 years or approximately 200,000 to 300,000 km.
