Spring Brake (S-Cam)
Bendix

The Spring Brake S-Cam assembly is a dedicated parking brake solution designed to hold the vehicle securely when parked and to release smoothly under service brake operation. Key measurements include a 180-degree clamp angle for versatile frame mounting, a 1.50 inch stud length, and a 3 inch stroke that defines how far the chamber can travel to apply or release the brake. The 4.75 inch stud distance and 5/8-18 UNF-2A stud thread provide compatibility with common mounting practices in heavy-duty hardware. The clevis is welded for rugged reliability, and the parking port uses a 3/8-18 NPTF thread, while the service port also employs 3/8-18 NPTF, ensuring robust pneumatic connections. The unit operates across a wide temperature range from -40 to 175 degrees Fahrenheit, making it adaptable to harsh climates and varying ambient conditions. The construction is described as S-Cam Spring Brake with a welded clevis and a 30/30 chamber, and the product attribute air port position is 0 degrees, implying straightforward integration with existing air line routing. VMRS 013-004-027 places this component within the spring brake category, while category 41368 highlights its role in parking brake systems that are critical for vehicle security and safety during loading, unloading, and rest periods. Cross-references are not listed, indicating a direct fit within standard fleet braking architectures.
