Abstract
A self-adjusting parking brake actuator includes a brake lever that is movable between brake-released and brake-applied positions. In addition, the parking brake cable adjust system includes a self-adjustment assembly having a frame; a rack mounted for movement relative to the frame along a longitudinal direction of the rack in a tension direction and an opposite direction; a cable connector for operatively connecting the rack to a brake cable, a first resilient member biasing the rack relative to the frame along its longitudinal direction in the tensioning direction, a primary locking device configured to engage the rack and permit movement of the rack relative to the frame in the tensioning direction only; a secondary locking device moveable between (a) a locking to lock the primary locking device to prevent adjusting movement of the rack relative to the frame in the tensioning direction, and (b) a releasing position to permit the primary locking device to allow adjusting movement of the rack relative to the frame in the tensioning direction by the biasing of the resilient member; and a second resilient member biasing the secondary locking device to the locking position.
