Product Details

Brembo 09.A621.31 is engineered as a direct replacement rotor that meets or exceeds OEM specifications for front brake service. The UV-coated surface is solvent-free and protects the disc, including the braking plate surfaces, which helps maintain appearance and resist rust. For Mercedes-Benz E350 front brake rotor replacement, Mercedes-Benz C350 front brake rotor replacement, and Mercedes-Benz E400 front brake rotor replacement, this rotor provides the dimensions and construction needed for proper OE-style service. This part cross-references Zimmermann 400.3654.20 and Raybestos Brakes 980793FZN for the same application.

What It Helps Address

• Brake pulsation from worn or uneven front rotors
• Noise and vibration during braking
• Surface corrosion on exposed rotor areas
• Reduced braking consistency from rotor wear
• Front brake service needs on select Mercedes-Benz E-Class and C-Class models
