Product details
An individual Wilwood DynaPro brake caliper, finished in anodized, is specified here. Use the 1.75/1.75-inch piston bores, 5.25-inch mounting centers and 0.81-inch rotor width to compare it with the existing brake assembly. 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. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement.

Fitment & Compatibility
Choose this component around the existing rotor and bracket, including the 0.81-inch nominal rotor width and 5.25-inch mounting span. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Compare pad support, caliper offset and piston volume with the brake being replaced. Wheel size alone cannot confirm spoke or barrel clearance.
