Wilwood Brake Proportioning Valves

Wilwood Brake Proportioning Valves
Adjust brake bias quickly.
Wilwood brake proportioning valves are adjustable between 100 and 1,000 psi with a twist of a knob or the flip of a lever, and can reduce pressure up to 57 percent. They let you adjust brake bias quickly and easily to compensate for changing track conditions, or for big and little tire combinations. Wilwood machines each proportioning valve from billet aluminum.

Proportioning valves are installed in the rear brake line and allow you to adjust the rate of pressure rise to the back brakes. With an adjustable proportioning valve, you can slow down the pressure rise that occurs when you apply the brakes. Under braking, most vehicles transfer more weight to the front wheels. When this happens, the rear wheels lose some weight and can lock up if the pressure is too great too quickly in the braking process. Eventually full pressure is applied to the rear brakes through the proportioning valve.
