Spring Brake S-Cam
Bendix

Spring brake S-CAM configuration delivers a specific chamber arrangement optimized for reliable actuation and brake shoe engagement in drum brake systems. VMRS 013-004-027 indicates its role within the spring brake components family, with cross references including 9482 3230051, ABP N42A 33030C3D, ABP N42A 43030C3D, HDX GC3030L, MGM 3230051, and SLV 3030SBLS, signaling broad compatibility across OEMs and aftermarket catalogs. The chamber is described as 30/30, a common designation for spring brake configurations that balance capacity and space requirements. The dimensional and mounting considerations support straightforward integration with standard yokes and brackets found on heavy duty trailers. Category 41368 situates this part within a focused market segment of spring brake systems designed for rugged service, quick maintenance, and predictable performance under high load and temperature variation. In practice, technicians rely on such S-CAM based assemblies to deliver rapid, consistent brake activation, minimize cycling resistance, and preserve system integrity across sustained service life, even in demanding highway or job site conditions.
