Wilwood 4 oz Reservoir Cap with Fluid Level Sensor, 2.34-Inch Float

This remote reservoir cap incorporates an electronic float to signal low brake fluid level in the matching Wilwood 4 oz reservoir. The 2.34-inch float length is specific to that reservoir depth; this is not just a plain sealing cap. For Wilwood Engineering's motorsport, street-performance, and specialized applications, component selection follows the requirements of the complete brake system. The company was founded by Bill Wood in 1977 and is based in Camarillo, California, where its business focuses on designing and manufacturing disc brake systems, calipers, rotors, master cylinders, valves, fittings, and lines.
