Wilwood 260-11179 – Floor-Mount Combination Proportioning Valve with Stop-Light Switch
A single, compact block that merges three critical brake-system functions in one lightweight aluminum housing:
-
an adjustable proportioning valve for the rear circuit
-
a front-circuit distribution block (1 inlet → 2 outlets)
-
an integrated stop-light pressure switch
Perfect for disc-brake conversions, race cars, kit builds, and any project where space, weight, and plumbing simplicity matter.
Key Features
-
Dial-in rear bias – knob adjusts rear pressure from 100 psi to 1 000 psi, letting you fine-tune balance for tire size, weight transfer, or track conditions.
-
Front / rear isolation – maintains separate circuits when used with any tandem master cylinder.
-
Built-in brake-light switch (1/8″ NPT) eliminates extra tees and wiring hassles.
-
CNC-machined 6061-T6 aluminum body with black anodizing resists corrosion and weighs far less than cast-iron OEM valves.
-
Common 3/8″-24 inverted-flare ports drop straight into most US brake lines without adapters.
