AP Racing screw type brake bias valve. These valves have been specially designed for use in competition vehicles where it is desired to reduce the hydraulic line pressure and therefore braking effort of the rear brakes to compensate for the varying surface conditions, tyre choices and vehicle set up. The lever type valve provides the driver or the co-driver with 7 distinct settings, with maximum adjustment giving an output pressure reduced to approximately a third of original input pressure. Strictly for competition use only.
