GM Prop Valve Kit Disc-Disc, PREMIUM kit & pig tail ( PV4) SPECIAL BUY

 Proportion / GM  Style brass distribution Block with bracket

for Disc / Disc applications

This is for a brand new brass Proportioning Valve and Side Bracket Mounting Kit with 1/2" Front and 9/16" Rear Brake Lines.  This combination proportioning valve is for Disc / drum applications.  This valve performs all the necessary functions when using disc brakes in the front and disc brakes in the rear including the following

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 valve is a great upgrade over the original and is a must when upgrading from drum to disc brakes.  This is a universal GM valve, and will work on almost any Chevy, Buick, Oldsmobile, Cadillac, Pontiac, or GM Trucks with a GM style Master Cylinder.  

This also includes the left Side Bracket Mounting Kit, which allows you to mount this to the Left (Driver's Side) of the master cylinder with or without any aftermarket or Stock Booster including 7" 8" 9" 10" and 11" sizes.  

Additionally, this  includes two hard lines that connect the master cylinder (with 1/2" & 9/16" ports) to the proportioning valve.  GM style master cylinder only
