Wabco 9254921030 (925-492-103-0) is a spring brake chamber assembly, Type 30/30, for S-cam drum brakes. A spring brake chamber holds the truck in place when parked and applies the brakes by itself if air pressure is lost, so it does double duty as the parking and emergency brake.
A weak parking brake, a truck that creeps while parked, or brakes that drag and release slowly point to worn parts inside the chamber. This one has a 65.0 mm stroke and a threaded clevis. Call us to confirm proper fit for your application. A genuine Wabco part from Pro Gear and Transmission.
