Product details
For a brake system using a 1.00-inch-wide rotor, this black Wilwood Dynapro Radial Dust Seal provides 4 pistons with 1.75-inch bores. The caliper attaches on 5.98-inch radial centers. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, 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
Measure rotor width before comparing calipers. Verify the mount height, rotor centerline and available wheel space; a common piston count does not establish interchangeability.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
With over 20 years of experience, PMB Performance can help compare piston configuration and mounting geometry. Share the existing brake package and measured rotor dimensions before ordering.
