MGM Brakes Double Diaphragm S-Cam Drum Brake, Piggyback Plus Kit, 2.5 in Stroke, 3/8-18 NPTF Port, Rubber Diaphragm, Tamper Resistant

The TR series is an industry standard double-diaphragm spring brake with the original tamper resistant safety design. This model can come with additional features such as an external breather tube system, epoxy-coated inside and out for extra protection in unusually tough, corrosive operating environments, extra parking force, and weld-reinforced mounting bolts to provide a stable, strong mounting base for installation on equipment where extreme vibration is a concern. The TR series is also available in a 3 in long stroke design, providing the reserve stroke needed for added braking safety. Piggyback Plus kits are available for some models.
