Product details
An individual Wilwood Dynalite Internal brake caliper, finished in anodized, is specified here. Use the 1.38/1.38-inch piston bores, 5.25-inch mounting centers and 0.38-inch rotor width to compare it with the existing brake assembly. This forged Dynalite Internal caliper uses four stainless pistons and internal fluid passages. It has the 7112 pad outline and a 5.25-inch lug mount. Compare the installed rotor width and piston bores before replacing a similar-looking Dynalite. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Components must be selected to suit the complete brake system.

Fitment & Compatibility
Match the 5.25-inch lug attachment to the existing bracket, then check caliper centering over the 0.38-inch nominal-width rotor. Axle placement is determined by the engineered brake package, not by a generic caliper designation. The 1/8-27 NPT connection must use the correct fitting and seal. Check the full wheel envelope with the actual bracket and rotor installed.
