ABSTRACT:
In order to improve an electrically actuatable automotive parking brake with mechanical emergency actuation, the brake pads (52, 54) of the parking brake, which may be either a disk brake or a drum brake, can be applied or released via gear arrangement (100) arranged within or at the brake. The gear arrangement (100) has one power input and one power output, with the power input being coupled with the one end of a flexible shaft, the other end of which being arranged remote from the brake can be coupled with a manual crank, in order to be able to actuate the parking brake mechanically in the case of a failure of the electric actuation.
