This is a new brass Disc Disc Proportioning Valve with Lines & Bracket for universal applications. 

PV4 Side Bracket + 1/2" and 9/16" Lines.

 

Comes with compatible disc/disc proportioning valve kit (self adjusting valve pre-bent lines for 1/2" and 9/16" master cylinder ports, bracket to mount kit to the side of the master cylinder, and bolts)

The proportioning / combination valve performs all of the necessary valving functions with a disc brake conversion…

 

Proportioning:

As more force is applied to the brakes the car will begins to lean forward, less braking force is needed in the rear. This valve decreases the pressure to the rear which prevents them from locking up.

• 1964-1988 Chevrolet Chevelle

• 1962-1979 Chevrolet Nova
