Bendix

An essential safety device within heavy-duty braking systems, this spring brake assembly provides parking and hold functionality by applying a high-force spring when air pressure is removed. The configuration supports a 20/30 chamber type, with service and parking ports sized at 3/8-18 NPTF and an air port orientation of 135 degrees to suit typical mounting envelopes. The stud length is 1.50 inches, and the stroke length is 3 inches, with a clamp angle specification of 45 degrees. Operating temperature ranges from -40 to 79 degrees Celsius, with a maximum operating temperature of 175 degrees Fahrenheit. Constructed for S-Cam braking systems, the unit is designed to deliver reliable parking and controlled release across a broad spectrum of operating conditions. VMRS code 013-004-027 places it squarely in the spring brake category, with compatibility across Bendix-based systems and a range of heavy-duty fleet applications, from long-haul transport to vocational service, where dependable parking brake performance is critical.
