Product details
This anodized Dynapro Radial Dust Seal uses four 1.62-inch stainless pistons, giving it the specified 4.12-square-inch hydraulic area. The larger bore configuration must be considered when matching brake balance, even when another radial Dynapro appears similar. Dust wipers, a forged aluminum body and a nominal 1.00-inch rotor-width channel define the individual caliper supplied here. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.
This four-piston radial Dynapro includes piston dust wipers. The radial mounting centers are common to several rotor-width and radius versions, so bracket height, pad sweep and actual rotor dimensions must all be compared.

Fitment & Compatibility
Use the 1.62-inch bore specification when checking master-cylinder capacity and the intended front-to-rear hydraulic balance. The rotor must meet the listed 0.94–1.04-inch width and 10.75–12.19-inch diameter limits, with the bracket locating the pad correctly on its swept surface. Before assembly, compare the 5.98-inch radial centers, mounting height and hose clearance with the installed brake package.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
