1964-72 A-Body, 1967-69 F-Body, 1968-74 X-Body Street Beast HydraStop complete hydraulic assist brake kit
CPP HydraStop systems are brand new hydraulic assist brake boosters designed to replace manual or vacuum assisted brake boosters in classic cars and trucks. All HydraStop systems are new units and are backed by a limited lifetime warranty when installed with a power steering filter. CPP PSFF-K and PO-OF6 filters are recommended, but other suitable power steering filters may be used.

HydraStop systems operate using hydraulic pressure from the vehicle’s power steering pump rather than engine vacuum and are capable of delivering up to 1800 psi at the wheels.

The CPP Street Beast HydraStop kit, part number 6474HBK-SB, is designed for 1964-72 A-Body, 1967-69 F-Body, and 1968-74 X-Body applications and mounts directly to the firewall.

Street Beast HydraStop kits use a black direct mount aluminum bracket and include black hydraulic hoses, a 1 1/8 inch bore aluminum master cylinder with black lid, a black adjustable brake valve, and a black accumulator cover. This HydraStop system is supplied with AN6 fittings installed.

Customer Questions
what type of power steering pump do i need for this?
The power steering pump recommended for this CPP HydraStop Hydraulic Brake (part # 6474HBK-SB) would be either a GM Type II or GM Saginaw type pump with a minimum flow of 2.25 GPM and 1200 PSI. 
What power steering fluid do you recommend for this part?
For this CPP HydraStop Hydraulic Brake Assist System (Part # 6474HBK-SB) we recommend using AC-Delco brand power steering fluid.
Instructions recommend a filter but do not say the best place to install it. I would think between the pump and the Hydrastop (Hi Pressure line) but CPPM sells the filter with push lock connectors which I assume are NOT for Hi Pressure lines. Where does the filter go?
Hello! The best place will be on the return hose to the reservoir, only due high pressure causing damaged to the filter.
