Wilwood Dynapro Radial Dust Seal Brake Caliper for 0.50-Inch-wide Rotor, 5.98-Inch Radial Mount, Black

The Wilwood Dynapro Radial Dust Seal shown here is specified for 0.50-inch rotor width, 5.98-inch radial mounting and 1.25-inch piston bores. This black 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

Compare the installed rotor’s nominal width with this exact caliper version. Before assembly, verify pad sweep, caliper-to-wheel clearance and the hose fitting’s thread and sealing method.

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.

PMB Performance has worked with parts and brake fitment for over 20 years. Supply the installed caliper identity and the rotor and bracket measurements for a practical compatibility check.
