This unit will give you great stopping power and features a Bendix OE style black 8" dual diaphragm power brake booster combined with a 1" bore dual reservoir master cylinder. Master cylinder has smooth flat top with 9/16" and 1/2" ports on both sides.
If your car or truck had a single bowl master cylinder this is a nice upgrade and much safer than the old single bowls often used. Some brake line work will be necessary.
Due to the wide range of vehicles this unit can fit; the firewall mounting bracket comes with a variety of extra rod extension / pedal attachments and spacers for adapting to numerous applications.
Kit includes:
A disc brake combination valve is a necessity when doing a drum to disc conversion. The combination valve will provide all the valving necessary in the system. Combination valves perform four functions...(1) Proportioning, (2) Metering, (3) Residual Pressure, and (4) System Failure Warning.
Proportioning:
As more force is applied to the brakes and the car begins to lean forward, less braking force is needed in the rear. This valve decreases the pressure to the rear, preventing lock up.
System Failure Switch:
This valve has a system failure switch that will alert you when half of your braking system is not working properly.
This also includes the Bottom Bracket Mounting Kit, which allows you to mount the proportioning valve beneath the master cylinder.
Additionally, this includes two hard lines that connect the master cylinder (with 1/2" & 9/16" ports) to the proportioning valve.
Note: This kit is designed for converting vehicles with manual master cylinder brakes or hydro vac systems to a vacuum power assist brake booster setup. This is NOT a direct replacement if you already have a booster and power brakes. When making such conversions to power brakes; it is not uncommon for some modifications to be necessary in order to complete installation.
