This NEW Hydro-Boost, hydraulically powered brake booster, fits Shelby Cobra and Cobra Kit/ Replica cars. There is normally a tight fit on these vehicles, so we offer two options that will cover your setup. If you have enough clearance from your fire wall forward, you can select the standard unit, the Hydro-boost is about the same length and diameter of a dual reservoir master, so check the space you have. If you don't have the room, then just select the remote mount option which allows you to mount the unit anywhere on your vehicle. The unit pictured is the remote mount booster, the firewall mount has a more conventional flat bracket. 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, no one else can.
The answer to all of the problems associated with high performance vehicles. The Bosch Hydro-Boost is more powerful than factory vacuum boosters, and smaller than the 7" hot rod booster and can generate 1200 to 2000 psi at the calipers. It accepts master cylinders from 15/16" to 1 5/8" bore sizes. We stock factory replacements boosters but also modify new units for retro-fit / conversion for vehicles that didn't come with them.
The Hydro-Boost is powered by pressure from the power steering pump and requires no vacuum. The other option is a vacuum pump with a small bore master cylinder that jacks up the pressure to the calipers, but small bore masters won't put out the volume needed to fill caliper pistons, and vacuum pumps won't keep up. You can also spend a lot of money on great big calipers, but they tend to be more demanding of volume and pressure, so they don't work unless you have a Hydro-Boost. It provides great valve cover clearance, and exhaust pipe clearance when frame mounted. The Hydro-Boost fits any where a vacuum booster does. It can use stainless braided hoses or rubber type. We have many direct replacements, our own retrofit applications, and can design anything else.
