Spring Brake (S-Cam)
Bendix

Spring brake (S-Cam) chamber designed for 24/30 configurations with a 45-degree clamp angle and welded clevis, 1.46 in stud length, 3 in stroke, and 4.75 in stud distance. The push rod length is 2.25 in, with matching 5/8-11 UNC-2A thread on the stud and 5/8-18 UNF-2A on the push rod. Push rod and service port interfaces use 3/8-18 NPT threading, and the parking port is likewise 3/8-18 NPT. The air-port position is 270 degrees, ideal for axle installations with limited clearance or specific routing constraints that favor a rear-oriented air-port layout. The temperature envelope remains -40 to 175 degrees Fahrenheit, ensuring reliable operation in varying weather conditions. This chamber type is suited for standard S-Cam brake systems where consistent actuation and predictable stroke are essential for maintaining pedal feel and rotor wear characteristics across heavy-duty applications.
