1-3/4 Inch Master Cylinder for Hydro-Max Brake System Iron Reservoir (1.75 inch, 44.45 mm)

The Bosch Hydro-Max brake system operates off of power steering pump pressure, and has an electric backup motor to supply you with brake assistance in case the engine dies. The Hydro-Max has come OE on most medium trucks since the mid 80's, that aren't full air-brake, including school buses, fleet vehicles, motorhomes, and construction equipment. Sweeting Performance also adapts them as a retrofit for older medium duty trucks that may have come with a Hydro-Vac, Dual Power, Hypower, or other brake system that can no longer be serviced. We carry many new genuine Bosch OE replacement Boosters, Master Cylinders, and Motors, and we also manufacture the small parts that make them fit one vehicle or another. We can offer you new replacements, rather than economy rebuilts, for applications that the factory, Ford, GM, International, or other manufacturer would say is obsolete, and we can also build them, as upgrades, for vehicles they never came on.
