ABSTRACT:
A slack adjuster for vehicle brakes is adapted to be mounted between the brake chamber and the brake operating shaft. The slack adjuster includes a body and a drive member movable relative to and positioned by the body on the brake operating shaft. A lever arm is pivoted to the body and there is an adjustable connection between the lever arm and drive member for the sensing and take up of slack during a brake application. The adjustable connection includes a clutch having facing and relatively rotatable clutch surfaces, each of which has opposing cooperating ratchet teeth. The teeth on one of said surfaces are separated into a plurality of radially spaced circumferential bands. The teeth in each band are positioned to independently engage the teeth on the opposing clutch face to provide increments of slack adjustment.
