A brake actuator for use in a motor vehicle having brakes actuable by a cable system with cables. The brake actuator includes a mounting bracket and an output member connected to the cables. The brake actuator includes an input lever mounted to the mounting bracket at a pivot for movement in brake applying and brake releasing directions. The pivot of the input lever is spaced axially from the output member and connected to the output member to effect movement of the output member. A plate is provided between the mounting bracket and the input lever and prevents contact between the mounting bracket and the input lever during movement between the brake applying and releasing directions. An additional plate is provided between the mounting bracket and a cover portion and prevents contact between the mounting bracket and the cover portion during movement between the brake applying and brake releasing directions.

Brake actuator with improved efficiency

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.

Parking brake cable and adjust system having no lost cable travel

The present invention provides for a brake actuator for use in a motor vehicle. In a motor vehicle with one or more brakes activated by a cable system, there is a mounting bracket mounted in the motor vehicle. Movably mounted to the mounting bracket is a lever that can move in brake applying and brake releasing directions, and which is constructed to be connected to the brake cables. The lever applies tension to the brake cables when the lever is moved in the brake applying direction, and releases the tension when moved in the releasing direction. Mounted to either the lever or the mounting bracket is a retainer constructed to engage the other of the lever or the mounting bracket. The retainer acts to restrict the relative lateral movement of the lever and the mounting bracket.
