Wilwood Forged Dynalite Internal Dust Seal Brake Caliper for 0.75–0.83-Inch Rotor Thickness, Red

Red finish and 1.75-inch bores distinguish this Wilwood Forged Dynalite Internal Dust Seal configuration. It is a 4-piston brake caliper for 0.81-inch-wide rotors, with 5.25-inch lug attachment centers. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

Piston dust wipers distinguish this sealed four-piston Dynalite Internal from the unsealed model. Its spacerless body and internal fluid transfer are matched to type 7112 pads and the selected rotor-width capacity.

Fitment & Compatibility

Compare the existing caliper’s piston area, rotor capacity and mounting pattern. Matching the body family alone does not guarantee that the replacement will clear the wheel or preserve pedal travel.

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