The Wilwood Brake Bias Proportioning Valve provides exceptionally precise and stepless adjustment of front-to-rear brake pressure. With a reduction range of 0 to 57%, it offers far more accurate control than conventional lever-style proportioning valves.
Installed inline with the rear brake circuit, the valve regulates rear brake pressure, allowing increased braking force at the front. This results in improved braking performance, enhanced stability, and reduced stopping distances, especially under racing conditions.
The fine-threaded adjustment shaft ensures fast, accurate response and allows for precise tuning. The valve is suitable for single master cylinder systems, as well as single or dual circuit brake setups, and can be adjusted directly from the cockpit.
