Wilwood Dynapro Radial Dust Seal, 4-Piston Radial Brake Caliper, Red, 1.25-Inch Bore for 0.81-Inch-wide Rotor

The Wilwood Dynapro Radial Dust Seal shown here is specified for 0.81-inch rotor width, 5.98-inch radial mounting and 1.25-inch piston bores. This red 4-piston component is selected by brake-system geometry rather than vehicle year alone. 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.

Fitment & Compatibility

Select pads by the specified friction shape and intended operating temperature. Check the wheel template with the actual rotor, hat and bracket before finalizing the installation.

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

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.

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.
