Product details
The Type III anodized Wilwood Dynapro Radial Dust Seal is a four-piston hydraulic caliper with 1.25-inch stainless bores and dust boots. In this configuration, the nominal rotor width is 1.00 inch and the radial mounting centers are 5.98 inches apart. Choose it by rotor capacity, pad location and hydraulic area, since other Dynapro variants can share the same attachment span. Wilwood Engineering’s disc brake range includes calipers, rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977 in California; it is based in Camarillo and serves motorsport, street-performance and specialized brake applications.
This four-piston radial Dynapro includes piston dust wipers. The radial mounting centers are common to several rotor-width and radius versions, so bracket height, pad sweep and actual rotor dimensions must all be compared.

Fitment & Compatibility
Center the caliper on a rotor measuring 0.94–1.04 inches wide and 10.75–12.19 inches in diameter. The bracket must accommodate the 1.61-inch mount height and locate the type 7816 pad sweep without overhang. Check the 1/8-27 NPT connection and compare the specified 2.46-square-inch piston area with the master cylinder and the other axle’s brake package.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
