Quality proportioning valve / distribution block (Combo valve) kit to easily add disc/drum function to your GM vehicle. Early Disc/Drum cars would have a separate prop valve and distribution block.  This newer style combo valve comes with all the necessary parts to convert your existing Drum/Drum brakes into Disc/Drum application. This is needed to ensure proper hydraulic pressure to the front and rear brakes.

For use with 9/16-18" & 1/2-24" Port Master Cylinders

Kit includes:

• Brass Proportioning Valve
• Steel Lines
• Zinc Bottom Mount Bracket (Mounts on bottom of the master cylinder)
• Proportioning Valve Plug
• (2) 3/8-24" ports for the front brakes
• (1) 9/16-18" port for the rear
• Dash warning light connector
• Hardware to mount proportioning valve.

This is not a direct bolt in kit.  You will have to reroute your brake lines to accommodate the new port outlets.  In some cases, fitting adapters may also be required.
