Spring Brake (S-Cam)
Bendix

This service-oriented parking brake component is designed to integrate with S-Cam brake configurations where reliability and repeatable actuation are essential. Dimensionally balanced for straightforward installation, it uses the same 45 deg port geometry and 150 deg clamp configuration to accommodate standard chassis layouts, while a 1.50 inch stud length with 5/8-18 inch thread provides durable attachment to the lever system. The stroke length remains at 3 inches, ensuring ample travel for accurate cam engagement and release during both parking and service cycles. Ports for parking and service are both 3/8-18 inches, enabling flexible plumbing routes for diagnostic tools or control circuits. The design preserves a broad operating temperature window from -40 to +79 C, maintaining performance across diverse climates and duty cycles. The double diaphragm chamber enhances redundancy and loading stability, translating to smoother brake application and longer service intervals in heavy-duty fleets. VMRS 013-004-001 identifies this as a key brake assembly component, facilitating cross-reference and compatibility checks. In practical terms, it supports steady, predictable braking behavior, reduces the risk of unintended engagement, and contributes to fleet safety and availability in transportation operations that demand rugged, maintenance-friendly components.
