Product Description
The Bendix 2770454 Hydro-Max II is a hydraulic power brake booster designed for medium-duty International/Navistar commercial vehicles equipped with Hydro-Max braking systems.
The 2770454 uses hydraulic pressure to provide power-assisted braking, reducing pedal effort while supplying the braking force required by heavier commercial vehicles. This version features an offset hydraulic inlet and offset pump-and-motor mounting configuration, helping distinguish it from similar Hydro-Max booster assemblies.
The unit uses a 3/4"-18 hydraulic inlet with O-ring tube seat and a 1/2-inch inside-diameter push-on return hose connection. Haldex identifies the remanufactured equivalent RV2770454X as a Hydro-Max II booster for IHC applications and lists the unit at approximately 6 lb.
The 2770454 is also associated with casting number 2771424 and a single-prong flow switch. Because several Hydro-Max units look similar, verify the original part number, casting number, inlet location, flow-switch configuration, and mounting arrangement before ordering.
