Cam
Bendix

In heavy duty drum brake actuation systems, a precision machined cam plays a critical role in translating rotational input into controlled linear force that presses the brake shoes against the drum. This component is designed to meet standard VMRS 013-001-031 specifications, ensuring compatibility with a broad range of compatible camshaft and brake actuation assemblies. Its robust construction supports sustained performance under demanding service conditions, delivering consistent engagement and predictable wear patterns across the braking cycle. In practice, this cam helps maintain uniform shoe contact, promotes balanced clamping force, and minimizes dynamic vibration that can lead to uneven wear or premature chamber fatigue. The result is improved braking response during normal operation, enhanced reliability on long hauls, and reduced maintenance intervals when matched with the correct spring and yoke hardware. Category context places this item within a comprehensive brake actuation family designed for trailers and heavy duty tractors, reinforcing its role in reliable fleet operations. Cross references are not listed for this entry, signaling direct OEM compatibility with standard drum brake assemblies. When inspecting or replacing components in the brake actuation train, technicians benefit from standardized fitment geometry, shared mounting patterns, and consistent performance characteristics across the vehicle’s braking system.
