1. A brake application system for vehicles, particularly for rail vehicles, comprising:
a wear adjuster constructed as a brake actuator;
a screw drive of the wear adjuster having a threaded spindle as a first screw part and a nut as a second screw part, the nut being configured to be screwed to the spindle;
at least one of the two screw parts is electrically driven for wear adjusting by an electric drive unit;
wherein the electric drive unit includes an electric motor having a gearing arranged on an output side, and a gearing output of the gearing is rotationally coupled with the at least one screw part that is electrically driven;
a slip clutch located between the electric drive unit and the at least one electrically driven screw part, wherein the slip clutch slips when at least one of two stop positions has been reached and otherwise the slip clutch is coupled; and
wherein a first of the stop positions is formed by an application of brake pads to a brake disc and a second of the stop positions is formed by an end position in which the at least one electrically driven screw part is screwed into the other screw part of the two screw parts to the second stop position or the other screw part of the two screw parts is screwed into the at least one electrically driven screw part to the second of the stop positions.
