MGM Brakes Tamper Resistant Piggyback Brake Chamber, 2.5 in Stroke, Epoxy-Coated, Breather Tube, 3/8-18 NPTF Port

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 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-inch long stroke design, providing the reserve stroke needed for added braking safety. Piggyback Plus kits are available for some models.
