Product details
For a brake assembly requiring the 0.81-inch rotor-width version, this Wilwood Aero6 left brake caliper provides the red configuration. Compare its radial mount and piston area with the component being replaced. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole braking system. Aero6 is a forged six-piston hydraulic caliper with internal fluid passages. Differential piston bores, radial bracket spacing and rotor dimensions determine the assembly. Select the pad compound separately for the operating temperature and use of the complete brake system.

Fitment & Compatibility
Match the 7.09-inch radial attachment to the existing bracket, then check caliper centering over the 0.81-inch nominal-width rotor. Use the left-hand caliper and keep the bleed arrangement in the specified orientation. The 1/8-27 NPT connection must use the correct fitting and seal. Check the full wheel envelope with the actual bracket and rotor installed.
