Wilwood 260-12627 – Adjustable Proportioning Valve with Brake-Light Switch
The Wilwood 260-12627 is a compact, knob-type proportioning valve that fine-tunes rear-brake pressure while housing an integrated brake-light pressure switch. The single-in / single-out design makes it perfect for disc-brake conversions, race cars and hot-rod projects where size, weight and quick adjustment matter.
Key Features
-
Stepless pressure adjustment – turn the knob to set the rear pressure cut-off anywhere between 100 psi and 1 000 psi, tailoring brake balance to vehicle weight, tyre grip and track conditions.
-
Single line in / single line out – installs only in the rear circuit; no need to replumb the entire system.
-
Lightweight 6061-T6 aluminium body with black anodising resists corrosion and tips the scales at roughly 170 g.
-
Universal 1/8″-27 NPT female ports accept common AN-3 hose ends or hard-line adapters.
-
Palm-sized footprint (86 × 24 × 38 mm) lets you mount it on the frame, firewall or even inside the cockpit for track-side tweaks.
