Abstract
A brake unit has a brake application device, a brake disc with a friction surface and a brake shoe with a friction lining which, during the actuation of the brake unit, acts by an application force Fs of the brake shoe on the friction surface of the brake disc. The friction surface of the brake disc is formed from a ceramic/metal composite material. A control device controls the application force Fs of the brake shoe during a braking procedure such that a defined braking torque results as a function of the application force. The brake shoe application force is increased by an increase in pressure such that an essentially linearly varying braking torque results. The invention also relates to a brake unit for carrying out this method by use of an electrohydraulic control device.
