Product details
Wilwood Dynalite Internal calipers must be matched by width and mounting configuration. This black brake caliper has 1.38/1.38-inch bore dimensions, a 5.25-inch mounting span and the 0.50-inch-wide rotor specification. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole braking system. 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.
