Wilwood Disc Brakes is pleased to announce two new Master Cylinder Reservoir Caps with Electronic Fluid Level
Sensors that will do away with having to manually check your brake fluid level. These new caps enable you to monitor
your brake fluid electronically and will indicate when fluid level needs attention, all from inside your vehicle.
The black caps are manufactured from durable lightweight Nylon with a high melting point and superior color fastness to
withstand the demands of engine compartment surroundings. The cap’s diaphragm provides positive sealing and long
service life in brake fluid environments. The internal float is made from a proprietary material, offering excellent
dimensional stability to yield accurate readings. Electrical connection is easy, using standard automotive 12V DC male
terminals.
Direct replacement caps are available for Wilwood’s most popular size threaded brake fluid reservoirs; order P/N 330-
12645 to fit both billet aluminum and molded plastic 4 ounce reservoirs, or P/N 330-12646 to fit the 7 ounce, 10 ounce and
10.7 ounce reservoirs.
Wilwood Electronic Fluid Level Sensor Caps are loaded with features and technology built from decades of domination in
world motorsports, and the proven reliability of Zero PPM defect quality supply to leading OE manufacturers around the
world. These caps not only enhance the appearance of your vehicle, but offer years of care free performance.
