Prop Valve Kit for Disc/Drum with Mtg Bracket- Lines

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 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. fit for GM style master cylinder only
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.
