Product details
This DynaPro radial caliper uses four 1.50-inch aluminum pistons protected by dust boots. The selected body has a nominal 1.00-inch rotor opening and a black anodized finish. It is a dimensional brake component, with 5.98-inch mounting centers and a piston area that must suit the existing hydraulic system. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.

Fitment & Compatibility
Match both the radial bracket and the 0.88–1.04-inch rotor thickness envelope. Check the 10.75–12.19-inch rotor diameter limits against the pad track, and leave adequate wheel clearance. Dust-booted pistons distinguish this part from competition versions that may share the general DynaPro shape.
