Wilwood Dynapro Lug Mount Brake Caliper, Type III Anodized, 4.80-Square-Inch Piston Area

This Wilwood Dynapro Lug Mount is a 4-piston brake caliper with a Type III anodized finish for a nominally 0.38-inch-wide rotor. Its 5.25-inch lug mounting centers and 1.75-inch piston bores must match the brake assembly. 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.

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

For a replacement, compare the entire caliper specification rather than the finish or logo. On an adapted system, establish rotor alignment and piston-area requirements before choosing the mounting bracket.

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

For a brake system assembled from individual components, PMB Performance brings over 20 years of experience. Contact us with the rotor, caliper and bracket information so we can help check the combination.
