Product details
For a brake assembly requiring the 0.50-inch rotor-width version, this Wilwood Dynalite Internal brake caliper provides the anodized configuration. Compare its lug mount and piston area with the component being replaced. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. Its disc brake design and manufacturing work includes master cylinders, valves, fittings and brake lines as well as rotors and calipers. The company serves motorsport, street-performance and specialized applications in which the entire brake system determines component choice. 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.

Fitment & Compatibility
Compare the caliper drawing with your lug bracket before ordering. The 5.25-inch mounting centers and 1.38/1.38-inch bores must suit the installed rotor offset and hydraulic system. Axle placement is determined by the engineered brake package, not by a generic caliper designation. A suitable pad sweep and clearance inside the wheel must be verified independently of rotor width.
