Product details
A 0.81-inch rotor-width specification and 1.38/1.38-inch piston bores identify this Wilwood DynaPro brake caliper. The anodized finish is applied to the exact component described below; match the mounting bracket before replacement. The DynaPro lug-mount caliper uses a forged body and top-supported 7812-shape brake pads. Its lug spacing, hydraulic bores and rotor width must match the existing assembly. Pad compound selection remains a separate decision from the pad backing-plate shape. 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
Verify the lug mounting interface and the complete rotor-width range shown above. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Account for the 1.38/1.38-inch bores when selecting the master cylinder and front-to-rear balance. Check that the 1/8-27 NPT fitting, flexline and wheel remain clear throughout their operating movement.
