Product Description
The Bendix 2772181 Hydro-Max II is a hydraulic power brake booster designed for medium- and heavy-duty commercial vehicles equipped with hydraulic braking systems. It uses hydraulic pressure to increase braking force, reducing pedal effort while providing dependable brake assist for trucks, buses, and vocational vehicles.
The 2772181 Hydro-Max II features an offset inlet port and is configured for use with a 2-inch bore master cylinder. It uses a 3/4"-18 hydraulic inlet with O-ring tube seat and a 1/2-inch ID push-on return hose connection. The booster is associated with casting number 2772114 and uses the 2771320-family electric motor pump.
This configuration was used in a variety of International/IHC, Chevrolet, GMC, Freightliner, and commercial bus applications. Because Hydro-Max systems were produced in several similar configurations, verify the original part number, casting number, master-cylinder bore, inlet position, and mounting arrangement before ordering.
