ABSTRACT:
A brake actuator shaft has a clutch on an inner end which drives a splined sleeve. The splined sleeve engages an inner projection to turn one piston part on another piston part and to effectively lengthen the piston part. When the shaft is turned by a brake lever, it operates an actuator which presses on the piston part and inward projection and which prevents further relative rotation of the piston parts, causing the clutch to slip. A gear on an outer surface of the rotating portion of the piston engages a pinion connected to a manual adjuster. A ratchet in the manual adjuster prevents rotation of the pinion and the gear in the piston shortening direction.
