Product details
This black Wilwood Aero6 left brake caliper uses a 7.09-inch radial mount and the 0.81-inch rotor-width configuration. It is sold as one caliper, with its piston and mounting specification selected for the complete brake assembly. 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. 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
Compare the caliper drawing with your radial bracket before ordering. The 7.09-inch mounting centers and 1.75/1.62/1.62-inch bores must suit the installed rotor offset and hydraulic system. Use the left-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.
