Wilwood Rear CPB Brake Kit for Fiat 500 (2012–2015), Black Calipers and Plain 11-Inch Rotors

The Wilwood CPB rear brake kit pairs plain-face 11-inch rotors with black combination parking-brake calipers for the listed 2012–2015 Fiat 500 applications. Hydraulic service braking and mechanically operated parking functions share the caliper, rather than requiring a separate parking-shoe assembly. This is a matched rear conversion package, including the application-specific flex-line kit, for a correctly balanced complete brake system. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company 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.

Fitment & Compatibility

Identify the exact 500 trim and year before choosing this package; Abarth, convertible and electric versions have separate application entries. The parking cable must operate the mechanical caliper mechanism correctly, with suitable adjustment and full release. Check the original hub, rotor-hat seating and hose routing during installation. A nominal 15-inch wheel is only a starting point: compare its spoke and barrel profile with the kit clearance drawing. Confirm front-to-rear hydraulic balance rather than choosing rear calipers by appearance alone.

Match the individual year, model, submodel and equipment conditions in the fitment table below.
