ABSTRACT:
A device for operating a parking brake including a pivotable lever for stretching a brake cable and a one-way locking mechanism for the lever having a pawl and ratchet teeth. The pawl is actuated by the balance of a spring force and the reaction force of the cable stretched so that the pawl is driven into engagement with the ratchet teeth by the reaction of the cable against the spring force when the cable is stretched beyond a predetermined tensioned condition.
