Wilwood Red CPB Rear Disc Brake Package, Fiat 500 (2012–2015), 11-Inch Drilled/Slotted Rotors

This Fiat 500 rear disc package uses red powder-coated CPB calipers with 11-inch drilled/slotted iron rotors. Its two-piece rotor construction places the friction ring on an aluminum hat, while the single-piston caliper provides both hydraulic braking and mechanical parking engagement. Wilwood supplies the pad and rear-line combination specified for this conversion; the original mounting geometry still determines fit. 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

Match the 2012–2015 application row to the car, paying particular attention to the separate cabriolet and Abarth listings. A compatible rear hub and the proper rotor position are essential; caliper color does not change those requirements. Verify cable end compatibility and lever movement before making final hose and cable connections. Check for full release after adjustment. Measure the proposed wheel against the Wilwood drawing with both its barrel and spoke shape considered, and review hydraulic balance with the installed front brakes.

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