Product details
The red left front Wilwood Aero6-DM is the six-piston caliper selected for the Tacoma's documented direct-mount conversion. It uses 1.62/1.38/1.38-inch bores, a 5.04-inch lug pattern and the nominal 1.25-inch rotor-width designation. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems for motorsport, street-performance and specialized use, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.
