ABSTRACT:
A brake adjuster wherein a thrust block is axially slidable in a cylinder bore and rotatably connected to one of two screw threaded adjuster members which are themselves interconnected by a self-sustaining thread. In use a power spring acts on the thrust block to move it axially within the cylinder bore to apply pressure to a friction pad via the adjuster members. The brake may be released by applying hydraulic pressure to the thrust block, at which time one adjuster member is rotated via a clutch, when a predetermined clearance has been taken up, relative to the other to adjust for pad wear. No relative adjustment occurs during application of the brake under the action of the power spring.
