Wilwood Electric Brake Line Shut-Off Valve, 12-Volt Solenoid for Racing Use

This solenoid-operated valve shuts off pressure delivery to a selected racing brake circuit when energized. Fluid can still return toward the master cylinder, so the valve does not trap applied pressure and must not be treated as a line lock or parking brake. From calipers and rotors to master cylinders, valves, brake lines and fittings, Wilwood Engineering's range covers disc brake systems and service components. Bill Wood founded the company in 1977; it is based in Camarillo, California and designs and manufactures for street-performance, specialized and motorsport applications. All component choices need to account for the complete system.
