Abstract
An electromechanical parking brake system is provided including an electric driving gear motor connected with a parking brake cable track member by a releasable connection, preferably in the form of a pawl and ratchet arrangement. In accordance with one feature of the invention, a manually-operable override device is provided for disengaging the pawl from the ratchet, thereby to disconnect the electric drive motor. According to another feature, the pawl is automatically disengaged from the ratchet when the cable track member is in the brake-released condition, so that a cable-tensioning device is actuated to remove slack from the parking brake cable.
