Wabco 4231050170 is a Type 20 air brake service chamber for drum brakes. It has a welded yoke clevis, a rear port with a brass fitting and a 2.50 in stroke.
In service, air pressure pushes a flexible diaphragm that drives the push rod out to apply the brake, and an internal spring returns the rod when the air is released. A chamber with a leaking diaphragm lets air escape and weakens braking, which is the usual reason to replace one.
This is a genuine Wabco part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
