Abstract: A brake wear adjuster is mounted within the bore of an actuator piston having a snap ring at the entrance of the bore. The adjuster includes a spring holder having a uniquely configured washer that is seated in a groove in the outer surface of the holder. A spring is carried about the holder between the washer and a flange at the opposite end of the holder. A pin having a mounted swage and a deformable swage tube are carried within the bore of the spring holder, the swage tube being movable with the holder while the pin and swage are stationary. Upon hydraulic fluid pressure being applied to the piston, the snap ring engages the washer and it in turn compresses the spring as it moves through the distance established in the groove. An occurrence of disk wear in the brakes causes the piston and holder to move further drawing the swage tube over the swage. Upon release of the pressure, the spring moves the washer and snap ring and thus also the piston to a retracted position to disengage the brake disks.
