Wilwood Side-Mount 15/16-inch Compact Master with NPT Outlet and Reservoir Options

This side-mounted Compact Remote master places its mounting bosses three inches apart and extends the pushrod to suit that layout. The fifteen-sixteenths-inch bore displaces a specified 0.77 cubic inch over the full stroke, with the fluid supply arranged through either included reservoir. For the manufacturer Wilwood Engineering, disc brake system design and manufacturing encompass calipers, valves, fittings, master cylinders, brake lines and rotors. Bill Wood founded the Camarillo, California company in 1977. Its motorsport, specialized and street-performance applications rely on components selected with the complete brake assembly and its operating requirements in view.
