Air Chambers & Components Overview

The brake chamber converts compressed air into the push-rod force that applies each wheel's brakes; spring (piggyback) chambers also hold the parking brakes. A leaking diaphragm or weak spring means reduced braking or a dragging brake. Van Horn Truck Parts carries service chambers and spring chambers cross-referenced to MGM, Haldex, Bendix, and Automann part numbers.

Match the chamber by type number (e.g., Type 24, 30, or 3030 combo), stroke (standard vs. long), and the port and mounting-stud configuration. Replace in axle pairs.
