Chamber Assembly - Spring and Service Brake, S-Cam
Bendix

This chamber assembly blends spring brake and service brake functionality in a single S-Cam package, featuring a welded clevis and a 30/30 chamber design. The 45 deg clamp angle and 4.75 in stud distance complement a 2.25 in push rod length, with 5/8-18 UNF-2A push rod threads and 3/8-18 NPTF ports for both service and parking lines. The air port is positioned at 270 deg, facilitating convenient hose routing in complex undercarriage layouts. A maximum air pressure of 150 psi aligns with standard service brake tolerances while maintaining reliable pedal feel and timely relay of braking force. Operating temperatures span -40 to 175 F, ensuring resilience in both hot climates and cold starts. VMRS code 013-004-027 is cited for consistent maintenance procedures, and cross references such as HDX GC3030LCW, MGM 3230951, TBB 151262, and WWS 3230951 help verify cross-compatibility with similar assemblies. Category context 41368 situates this as a versatile option for serviceable, welded-clevis drum brake systems in commercial trucks and vocational fleets.
