Brembo 08.5085.1X Disc Brake Rotor - Rear

Brembo Rear Drilled Rotor for Fiat 500

The Brembo 08.5085.1X is a rear disc brake rotor built as a direct replacement for select Fiat 500 models from 2012-2019. It combines a drilled braking surface with a UV-coated finish to support corrosion resistance and consistent braking performance.

Compatible with 2012-2019 Fiat 500 rear brake applications, this Brembo Premium Xtra Cross Drilled UV Coated Rotor is engineered to meet or exceed OEM specifications while maintaining a clean, service-ready appearance.

Product Details

Brembo’s Premium Xtra Cross Drilled UV Coated Rotor line focuses on OE-style replacement fitment with added surface protection and braking consistency. The UV coating is solvent-free and protects the disc, including the braking plate surfaces, while the high carbon cast iron design used where applicable helps reduce noise and vibration. For brake service, Brembo recommends replacing rotors and pads together to restore braking performance. This rotor is a strong match for Fiat 500 rear brake service where a drilled, corrosion-resistant replacement is required. The 08.5085.1X also cross-references DuraGo BR901086 for the same application.

Common Issues This Rotor Addresses

• Rear brake pulsation from worn or uneven rotor surfaces
• Corrosion on the braking surface or rotor hat area
• Brake noise caused by rotor wear or surface irregularity
• Reduced braking consistency from rotor thickness loss
• Service replacement for a damaged or out-of-spec rear rotor

Installation Notes and Tips

Verify rear fitment by year, make, model, and position before installation. Inspect pads, caliper hardware, and hub surfaces during service, and replace pads with the rotor when restoring braking performance. Confirm rotor thickness against the minimum thickness marking before reuse or replacement. Follow the specified torque value of 98 Nm during installation.

Quality Assurance

Brembo manufactures this rotor as a direct replacement designed to meet or exceed OEM specifications. The UV-coated finish, drilled surface, and cast iron construction reflect Brembo’s focus on braking durability, fit, and consistent service performance.
