Combination Proportioning Valve
The Combination Proportioning Valve substantially simplifies mounting, plumbing, wiring and brake proportioning adjustments on vehicles with dual circuit braking systems. The combination block maintains full isolation between front and rear fluid circuits and can be used in conjunction with any tandem outlet or dual mount master cylinder assemblies. The rear circuit has a single inlet and single outlet with the adjustable proportioning valve. Pressure adjustments range from 100-1000 PSI and provide for a maximum decrease of 57% in front to rear line pressure, the most of any available valve. Adjuster knob with fine thread tuning provides precise pressure adjustment. This adjustment lets you fine tune the front to rear braking balance by proportionally decreasing the rear brake line pressure. The front circuit has a single inlet with two outlets. It can be run as a single outlet with one outlet plugged, or used to split the plumbing on its way to the front brakes. A fluid port with a brake pressure switch responds instantly in the front fluid circuit for brake light activation. A wiring pigtail and a protective boot is included with the kit. Easy to install as the valves inlet and outlet ports are 3/8-24 SAE inverted flare seats.
