It provides service braking via an air-applied double diaphragm and spring-applied parking/emergency braking in one unit. This chamber is replaced when diaphragms leak, the power spring weakens, or corrosion affects the housing, leading to brake drag or loss of holding force. It includes an externally stored release bolt for emergency caging and a corrosion-resistant aluminum center case with an epoxy-coated head.
