Product details
A 0.38-inch rotor-width specification and 1.38/1.38-inch piston bores identify this Wilwood Dynalite Internal brake caliper. The black finish is applied to the exact component described below; match the mounting bracket before replacement. 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. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement.

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.
