Wilwood Red Dynapro Dust Seal Brake Caliper, 0.81-Inch Rotor Width

Choose this Wilwood Dynapro Radial Dust Seal when the installation calls for 1.62-inch pistons and 0.81-inch rotor width. The red 4-piston body uses a 5.98-inch radial pattern; check its complete geometry before substituting another caliper. 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

Plan the caliper installation with the rotor centered in the pad gap. Verify attachment hardware, hose connection and accessible upper bleeders, then confirm the brake system’s hydraulic balance.

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