40 to 81 Jeep Hydro-Boost Brake Booster
This NEW Hydro-Boost, hydraulically powered brake booster, fits 1940-1981 Jeeps. It comes in standard black but chrome and powder coat options are available. It uses New Bosch brake components, we are contracted directly with Bosch and can guarantee authenticity, and no one else can.
The Hydro-Boost is smaller then the 7 and 8-inch boosters and generates 1200 to 2000psi to the calipers. Many masters can be fitted to it, from the 15/16-inch to 1 5/8-inch bore sizes. It is powered by pressure from the power steering pump and requires No Vacuum. Most performance modifications made to engines rob vacuum, leaving a fast car with no brakes.
The advantages are that no "small bore" master is required, firewall and valve cover clearance is increase, and frame mounted Hydro-Boosts are the same width as a master cylinder giving additional exhaust pipe clearance. The Hydro-Boost can be fitted anywhere a vacuum booster will fit.
It can use stainless braided hoses or rubber type. Brackets are available for most applications, we engineer new ones all the time, you can call us to prototype an application for anything you do not see posted, and we have a set of 2 bolt and 4 bolt universal mounts that will fit nearly anything.
