A cable lock and release apparatus significantly reduces release efforts in cable lock mechanisms, as used in parking brake systems of a motor vehicle. The apparatus includes a cable actuator (20) rotatably disposed on a cable actuator shaft (26) and having a cable (22) attached to it. The cable actuator (20) includes a sector (28) having a plurality of sector teeth (30). A pawl member (32) includes a slotted pawl aperture (36) allowing rotation and translation of the pawl member about a pawl member shaft (31). A pawl tooth (34) is disposed on the pawl member for engagement with the plurality of sector teeth. A release means is provided for maintaining the pawl tooth in an engaged relationship with the plurality of sector teeth with the cable in the high tension position and releasing the pawl tooth from the engaged relationship with the plurality of sector teeth allowing the cable to return to the low tension position.
