Product details
The 7.09-inch radial attachment distinguishes this left Wilwood Aero6 brake caliper. This individual anodized unit is built for the 0.81-inch-wide rotor configuration and requires accurate alignment with the mating rotor and bracket. 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, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another.

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.
Wilwood caliper specifications
For a modified brake system, provide its existing component specifications along with the vehicle details. PMB Performance has over 20 years of parts and fitment experience to help check the assembly before purchase.
