Brake Chamber
Bendix

Brake chamber assembly designed for standard 24/30 S-Cam spring brake configurations, featuring a 45-degree clamp angle and a 1.46 in stud length. The 3 in stroke and 4.75 in stud distance define the hardware geometry for reliable actuation across the range of brake sizes used on heavy trucks. Push rod length is 1 in, with 5/8-11 UNC-2A threaded studs and 5/8-18 UNF-2A threaded push rods, ensuring solid engagement with the brake linkage. Parking port uses 3/8-18 NPT threading along with a 3/8-18 NPT service port, simplifying air-line connections in retrofit or replacement scenarios. Temperature tolerance spans -40 to 175 degrees Fahrenheit, supporting operation in extreme environments. The chamber is rated for a 135-degree air-port position to accommodate specific axle layouts and plumbing paths. Cross references are not listed, but the geometry is consistent with widely adopted spring-brake standards, making this chamber a reliable choice for restoring braking force with predictable modulation and stroke.
