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 screw type offers infinite adjustment at the limits of normal brake operation. With the cap screwed fully in no reduction in output pressure occurs, with the cap screwed fully out, the output pressure is reduced to approximately a third of input pressure. Strictly for competition use only.
- Fitted inside the car for easy reach and adjustment
- Precision cast valve body with integral mounting points
- Almost infinite adjustment with reduction up to two thirds
- Designed for use in most motorsport vehicles as required
