A method and a control system for applying defined clamping forces in a brake that is electrically operable by an actuator and includes a first friction surface and a second friction surface in between which a clearance is allowed, wherein the application 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 and clamping force, and wherein values of the clamping force as well as of the actuator position measured by a clamping force sensor and a position sensor are determined. To optimize the time-consuming initialization of the sensors used to determine the clamping force and the actuator position and, respectively, to take into account the non-linear rigidity characteristic of the system the control concept, the present invention discloses having the correlation described by a mathematical model whose parameters are determined during actuation.
