The Alltrux ATX1824.D Spring Brake Chamber is a heavy-duty Type 18/24 air brake chamber engineered for commercial truck air brake systems. This unit replaces OEM K132352BXW and equivalent Bendix-style spring brake chambers used in parking and emergency brake applications on heavy-duty tractors, trailers, and vocational trucks.

Designed for dependable performance in fleet and owner-operator applications, this Type 18/24 spring brake chamber combines both service brake and parking brake functions into a single sealed assembly. The service side delivers consistent brake response under normal air pressure operation, while the high-tension internal spring automatically applies the parking brake if system air pressure is lost.

Commonly cross-referenced with Bendix, Haldex, Meritor, OTR, and MGM style brake chambers, the ATX1824.D is built to match OEM mounting dimensions and performance requirements. Its reinforced diaphragm, corrosion-resistant housing, and heavy-duty construction make it ideal for demanding over-the-road, regional haul, and vocational environments.

If you're replacing a worn or leaking spring brake chamber, this direct-fit aftermarket replacement restores proper air brake system function and parking brake reliability in heavy-duty truck applications.

Professional installation is strongly recommended due to the high-energy internal spring mechanism.
