Product details
With 4 pistons and 1.62/1.62-inch bore dimensions, the anodized Wilwood Dynalite Internal brake caliper must be matched to the brake system rather than selected by finish alone. Its 1.00-inch rotor-width specification is separate from rotor diameter. 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. 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.

Fitment & Compatibility
Match the 5.25-inch lug attachment to the existing bracket, then check caliper centering over the 1.00-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.
