Wilwood Dynapro Lug Mount Brake Caliper for 0.25–0.38-Inch Rotor Thickness, Type III Anodized

For a brake system using a 0.38-inch-wide rotor, this Type III anodized Wilwood Dynapro Lug Mount provides 4 pistons with 1.38-inch bores. The caliper attaches on 5.25-inch lug centers. 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.

The lug-mount Dynapro combines four pistons, internal fluid passages and top-access type 7812 pads. Its 5.25-inch mounting centers support adapted brake systems, with rotor offset and hydraulic balance checked separately.

Fitment & Compatibility

Check pad depth against the rotor’s usable friction annulus. Rotor-hat clearance, mounting offset and the wheel’s inner profile must also be checked with the caliper drawing.

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