ABSTRACT:
A drum-type brake and actuating system therefor comprised of a camshaft, cam and actuator mechanism that are contained within an actuator housing and a tubular shaft which journals the camshaft. A lubricant fitting permits lubricant to be introduced into both the tubular member and the actuator housing. In addition, an automatic adjuster is contained within an adjuster housing which communicates with the actuator housing and a pressure responsive valve that permits lubricant introduced through a grease fitting to be discharged from the adjuster housing. An expandable member is contained within the actuator housing for compensating for effective volume variations and precluding the exhaust of lubicant and the introduction of air during such changes.
