An actuator for use in a brake caliper is situated at opposite ends of a screw mechanism. A reduction gear mechanism is located at a distance from the actuating member. The reduction gear mechanism is included in a reduction gear module and a screw mechanism is contained in a screw mechanism module, which are interconnected through a drive module. The drive module may be located at the end of the reduction gear module facing away from the screw mechanism module. The modules may be axially aligned or at least two modules may be axially shifted or eccentric with respect to each other. The screw mechanism module may comprise an angular contact bearing which may be supported in a housing in different ways. The reduction gear module may be part of a planetary gear system.
