Performance Online Inc. 1947-53 1st series Chevrolet and GMC truck Hydro Boost® power brake booster kit is even smaller then the 7" or the 8" vacuum booster in use currently.

Generates 1000 to 1800 psi to the calipers depending on the volume of fluid transfer from master cylinder.

The Hydro-Boost® is powered by hydraulic pressure from the power steering pump. It requires 'no vacuum'. This has several advantages. No external vacuum pump required on low vacuum high performance motors. No 'small bore' master required. Firewall and valve cover clearance is increased. Frame mounted clearance is increased.

Frame mounted Hydro-Boosts® are the same width as a master cylinder, giving additional exhaust clearance.
The Hydro-Boost® can be fitted any where a vacuum booster will fit. It can use stainless braided hoses or rubber type and brackets are available for most applications.

The Hydro-Boost® uses fluid pressure from the existing power steering pump. The average power steering pump puts out from 800psi to 1400psi. The Hydro-Boost® uses this pressure that is always circulating through it, to convert to pressure to apply against the master cylinder. The output of the Hydro-Boost® is affected by three factors.

1. The pedal ratio. We prefer that the pedal ratio be between 4:1 to 6:1.
2. The pressure output from the pump.
3. The master cylinder bore diameter. These are factors necessary to design the system that will work for a given application.

We offer a one year warranty. Any metallic residue found in the unit will void warranty.

Kit includes:
• Hydro Power brake booster
• Master cylinder
• Prop valve (disc applications only)
