Combination Proportioning Valve
P/N 260-11179
GENERAL INFORMATION:
• Simplifies mounting, fluid circuit plumbing, brake light wiring, and brake bias adjustments on modified, custom built, or competition
vehicles equipped with brake system upgrades
• Maintains full separation between the front and rear fluid circuits when used with tandem outlet or dual mount master cylinder
assemblies.
• Bias proportioning adjustment is provided in the rear fluid circuit.
• The front circuit has a single inlet and two outlets for optional line routing.
• A fluid port with a pressure switch responds instantly to pressure in the front fluid circuit for brake light activation. A wiring pigtail with
a protective boot is included with the switch.
NOTE: Although the combination valve may mount in some OEM locations, it is not a direct replacement for any OEM unit and may
require modifications to the brake lines and/or the mounting location for installation. Bias proportioning adjustments will be specific
to each vehicle.
INSTALLATION INSTRUCTIONS:
Mounting: If equipped, the OEM combination valve bracket may provide the ideal mounting location for the combination valve.
Otherwise, position the Wilwood Adjustable Combination Proportioning Valve in a convenient location in close proximately to the master
cylinder(s) using customer supplied hardware or a fabricated bracket.
Line Connections: The line connections on the Wilwood combination valve are 3/8-24 with an SAE inverted flare for standard 3/16”
(-3) brake line. The supplied tube nuts can be double flared onto any 3/16” brake line. However, if your lines are already flared with
3/8-24 fittings, then the tube nuts are not necessary.
1. The line from the master cylinder for the front brakes connects to the port marked “FI”, (front in), on the top of the combination
valve, refer to Figure 1.
2. The two ports on the bottom of the valve marked “FO”, (front out), will be the supply lines to the front calipers. These ports can be
used to run individual lines to each caliper. Or if preferred, one port can be blocked, and a single line run from either “FO” port to
a “T” plumbed downstream, splitting the lines to feed each front caliper. The function of the valve will not change.
3. The line from the master cylinder for the rear brakes connects to the port marked “RI”, (rear in), on the top of the proportioning
valve.
4. The single port marked “RO”, (rear out), connects to the line going to the back of the car to feed the rear calipers.
NOTE: Tube wrenches are always preferred for tightening the fittings.
