Adjustable Brake Proportioning Valve

These proportioning valves are made of aluminum and provide an easy adjustment for setting front to rear brake bias when using a front disc brake system.  Whether you have drums or discs in the back you can change bias simply by turning the knob in or out to decrease or increase rear brake line pressure.  Easily mounted under the hood in a similar to stock location, or in the drivers compartment within reach for adjustment while driving.
