Abstract: A parking brake actuator having a mounting bracket, an actuation lever, a cable, a cable reel, a tensioning spring, and a clutch. The clutch is configured for coupling the cable reel to the actuation lever when the actuation lever is pivoted to the working position and uncoupling the cable reel from the actuation lever when the actuation lever returns to the rest position. The clutch includes a first grip face fixed to the cable reel, a disk that is slidable along the pivot axis, the disk having a second grip face and being biased axially to have the second grip face engage the first grip face, and a driver that is fixed to the mounting bracket, wherein the driver axially moves the disk to disengage the second grip face from the first grip face when the actuation lever is in the rest position.
