Product details
A 1.30-inch rotor-width specification and 1.75/1.38/1.38-inch piston bores identify this right Wilwood AV6R-ST brake caliper. The anodized finish is applied to the exact component described below; match the mounting bracket before replacement. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement. 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.

Fitment & Compatibility
Compare the caliper drawing with your radial bracket before ordering. The 7.09-inch mounting centers and 1.75/1.38/1.38-inch bores must suit the installed rotor offset and hydraulic system. Use the right-hand caliper and keep the bleed arrangement in the specified orientation. A suitable pad sweep and clearance inside the wheel must be verified independently of rotor width.
