The internal braking surface receives friction from the shoe lining, turning air brake actuation into wheel slowing at the hub. Cast iron mass absorbs heat generated during repeated stops, while the mounting pattern ties the drum to the wheel-end hardware. Pilot and bolt-circle dimensions are checked during installation, so the drum has to match the hub layout before service work continues. Wheel-end brake work installs the Automann 151.27503 where its drum size and hub pattern match the brake assembly.
Brake Drum, 12.250 in. x 7.500 in.
