Wilwood Dynapro Dust Seal Caliper, 1.00-Inch-wide Rotor, Type III Anodized 4-Piston Body

For a radial brake assembly using a nominally 1.00-inch-wide rotor, this Wilwood Dynapro Radial Dust Seal provides four 1.75-inch stainless pistons with dust boots. Its Type III anodized forged aluminum body attaches on 5.98-inch centers. Compare the complete mounting geometry before replacing another Dynapro version. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

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

Check the caliper-to-bracket attachment and rotor offset before ordering. Changing piston diameter changes hydraulic requirements even when a different caliper shares the same bolt spacing.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
