Product Details

Brembo 08.5178.31 is engineered as a direct replacement rotor that meets or exceeds OEM specifications for rear brake service. The UV-coated finish helps protect the rotor from corrosion, including the braking plate surfaces, while the grey cast iron material supports smooth operation and reduced noise and vibration. This rotor is a practical choice for drivers servicing Mercedes-Benz C230, C240, SLK230, SLK320, and related rear brake applications, as well as the Chrysler Crossfire rear brake setup.

The Brembo Premium UV Coated OE Equivalent Rotor line focuses on replacement parts that match original fit and function while adding a protective coating for long-term durability.
