MGM Brakes Heavy-Duty Combination Air Disc Double Diaphragm Brake, Chamber Size 18, Spring Size 24, M16 x 1.5 Mounting Stud, 2.5 in Stroke Length

TRB double diaphragm spring brakes offer the added feature of an “External Breather-Tube” that vents air from the inside protected area of the service chamber to effectively prevent entry of liquid and solid contaminants that can cause premature failure of the spring brake chamber, and a heavy-gauge formed steel mounting base, making the TRB model the perfect choice for tough operating environments. Stainless steel push-rod assemblies are also available as an optional feature which eliminates the possibility of corrosion at the push-rod and dust boot interface, providing additional caliper moisture intrusion protection.
