Product details
A black forged Aero6-DM body provides the left front caliper in this Wilwood Toyota Tacoma application. Its 5.06-square-inch effective area and six differential pistons need to be maintained when replacing a component in the existing conversion. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977; its motorsport, street-performance and specialized range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines.
