Wilwood Rear Brake Proportioning Valve, Knob Adjustable, 3/8-24 Inverted-Flare Ports

This adjustable valve reduces rear-circuit pressure to set front-to-rear brake balance in a custom system. Its 3/8-24 inverted-flare inlet and outlet accept the matching 3/16-inch double-flared brake tubing without separate tube-nut adapters. For motorsport, street-performance and specialized applications, Wilwood Engineering designs and manufactures disc brake systems and their components. The Camarillo, California company was founded by Bill Wood in 1977. Its range of rotors, calipers, valves, fittings, brake lines and master cylinders supports assemblies whose individual parts must be selected to work together.
