Wilwood Dynapro Radial Dust Seal Brake Caliper, Red / 1.25-Inch Bore / 0.50-Inch Rotor Width

Match this red Wilwood Dynapro Radial Dust Seal to a brake assembly requiring 0.50-inch rotor width and 1.25-inch pistons. The 4-piston caliper uses 5.98-inch radial mounting rather than a vehicle-specific adapter supplied as a kit. Wilwood Engineering’s disc brake range includes calipers, rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977 in California; it is based in Camarillo and serves motorsport, street-performance and specialized brake applications.

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

Set up the brake assembly around the specified rotor and pad geometry. Check the mount drawing and wheel envelope, and confirm that the piston area suits the rest of the hydraulic system.

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