1. Method of applying defined clamping forces in a brake that is electrically operable by means of an actuator and includes a first friction surface (friction lining) and a second friction surface (brake disc) in between which a clearance is allowed, wherein the application of the first friction surface against the second friction surface is determined, and wherein a static correlation exists between its actuating travel or, respectively, the actuator position (j actual ) and the clamping force (F actual ), and wherein values (F meas, j meas ) of the clamping force as well as the actuator position are determined, the values being measured by means of a clamping force sensor and a position sensor, characterized in that the correlation is described by a mathematical model whose parameters are determined during actuation.
