Brake proportioning valve which reduces pressure to allow the adjustment of brake bias via the adjuster knob. It is adjustable within its range of zero to maximum 57% pressure reduction. The valve has 1/8 NPT inlet and outlet ports and is supplied complete with two 1/8 NPT male to 3/8 UNF inverted flare female adaptors. The valve body as two mounting holes suitable for 1/4" or M6 bolts on a spacing of 1" (25.4mm).
INSTALLATION & ADJUSTMENTS: Proportioning valves are normally installed in the rear fluid line to prevent the rear wheels from locking before the front wheels, or to give the driver the ability to make fine adjustments in front to rear bias percentage on the track to compensate for tire wear, fuel load burn-off , or changing track conditions. It is generally not recommended to reduce front wheel braking capacity.
Two 1/8”-27 NPT to 3/8”-24 Inverted flare fittings are supplied to install 3/16” double flared hard brake lines to the valve. Connect the “IN” port to the pressure line coming from the master cylinder, connect the line going to the calipers to the “OUT” port.
Rotating the adjuster knob clockwise until it is all the way in will provide full pressure delivery to the calipers.
Rotating the knob anti-clockwise will incrementally reduce line pressure up to 57% when the valve is fully out.
If this range of adjustment is not sufficient to properly balance the vehicle’s bias, changes to other components within the system may be necessary.
