Wabco 4253301010 is a genuine Wabco air chamber, Type 18/24 with wedge operation and a steel body. Compressed air pushes on a diaphragm, which drives the pushrod outward to apply the brake, and a return spring brings it back when the air is released. Stroke is listed at 2.09 / 2.09 in, maximum operating pressure at 145.04 / 123.28 psi, and the port thread is M16 x 1.5. A leaking or ruptured diaphragm cuts braking force at that wheel, so audible air leaks, dents, corrosion or bent pushrods are reasons to replace a chamber. A genuine Wabco part from Pro Gear and Transmission.
