Product details
For a brake assembly requiring the 1.30-inch rotor-width version, this Wilwood AV6R left brake caliper provides the anodized configuration. Compare its radial mount and piston area with the component being replaced. AV6R is a forged six-piston radial caliper with a specific bracket offset. This exact unit must be selected by its piston material and bore combination as well as rotor width; the AV6R range contains configurations that are not interchangeable. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. Its disc brake design and manufacturing work includes master cylinders, valves, fittings and brake lines as well as rotors and calipers. The company serves motorsport, street-performance and specialized applications in which the entire brake system determines component choice.

Fitment & Compatibility
Match the 7.09-inch radial attachment to the existing bracket, then check caliper centering over the 1.30-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.
