Abstract
A self-adjusting parking brake actuator includes a brake lever that is movable between brake-released and brake-applied positions. A self-adjustment assembly connects to the lever and includes a rack, a pinion, and a clutch. The toothed rack mounts to the lever for movement relative to the lever along a longitudinal direction of the rack. The rack connects to a brake cable and is resiliently biased in a tensioning direction. The rotatable pinion continuously meshes with the toothed rack. The clutch engages to prevent the pinion from rotating when the brake lever is in its brake-applied position, and disengages to allow the spring-biased rack to take up slack in the brake cable when the lever is in its brake-released position.
