Product details
An individual Wilwood Narrow DynaPro brake caliper, finished in red, is specified here. Use the 1.38/1.38-inch piston bores, 4.75-inch mounting centers and 0.81-inch rotor width to compare it with the existing brake assembly. Narrow DynaPro uses four stainless pistons, radial mounting and the thin 7812 pad outline. Internal passages and replaceable bridge wear plates are part of the design. Compare rotor width, pad thickness and mounting height with the existing brake before substitution. 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
Compare the caliper drawing with your radial bracket before ordering. The 4.75-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.
Wilwood caliper specifications
For a modified brake system, provide its existing component specifications along with the vehicle details. PMB Performance has over 20 years of parts and fitment experience to help check the assembly before purchase.
