Wilwood Fiat 500 Rear Brake Upgrade (2012–2015), Red Parking Calipers, Plain 11-Inch Rotors

Plain-face rotors and red hydro-mechanical calipers define this Wilwood rear brake conversion for the listed Fiat 500 models. The 11-inch vented friction rings work with BP-10 pads, and the CPB mechanism retains a mechanically operated parking function within each hydraulic caliper. Supplied flex lines are specific to this rear kit; the package must be installed with the correct original hub and vehicle configuration. 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

Use the table to distinguish the 500 body style, year and trim, including the separately listed electric and turbocharged applications. Inspect hub condition and confirm the rotor hats seat correctly before setting caliper alignment. Route the lines without tension at suspension travel limits and secure the parking cables away from moving parts. Parking levers must return fully to prevent drag. Confirm wheel-to-caliper clearance using the installation template, since not every 15-inch wheel provides the same internal space.

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