Brembo 09.R103.11 UV Coated Vented Front Rotor for Mercedes-Benz GL/ML/R-Class

Vehicle Fitment

• 2007-2008 Mercedes-Benz GL320 CDI (X164, 3.0L V6 Turbo Diesel, 4MATIC)
• 2010-2012 Mercedes-Benz GL350 BlueTEC 4MATIC (X164, 3.0L V6 Turbo Diesel, 4MATIC)
• 2007-2012 Mercedes-Benz GL450 (X164, 4.7L V8, 4MATIC)
• 2008-2012 Mercedes-Benz GL550 (X164, 5.5L V8, 4MATIC)
• 2007 Mercedes-Benz ML320 CDI (W164, 3.0L V6 Turbo Diesel, 4MATIC)
• 2008-2011 Mercedes-Benz ML550 (W164, 5.5L V8, 4MATIC)
• 2010-2012 Mercedes-Benz R350 4MATIC (W251, 3.5L V6, 4MATIC - 7-Passenger models)
• 2010-2012 Mercedes-Benz R350 BlueTEC 4MATIC (W251, 3.0L V6 Turbo Diesel, 4MATIC - 7-Passenger models)

Fitment Notes

• Fits the X164 GL-Class and W164 ML-Class platforms; does not fit the W164 ML320, ML350, or ML450 - those applications use a smaller 330mm front rotor (see Brembo 09.R104.11).
• R-Class (W251) fitment applies to 7-passenger configurations only; 6-passenger R350 models use a different front rotor diameter.
• Sold individually (1 rotor per pack) - order two for a complete front axle replacement.
• Replaces Mercedes-Benz OE# 1644210512 / A1644210512 / 1644211412 / A1644211412.

Features

• Full-surface UV coating protects braking faces, outer diameter, and internal venting chambers against corrosion.
• High-carbon cast iron construction reduces noise and vibration while improving thermal conductivity for consistent stopping power.
• Internally vented disc design promotes superior heat dissipation, reducing brake fade during heavy or repeated braking.
• ECE R-90 certified - meets or exceeds Mercedes-Benz OE safety and performance specifications.
• Precision-balanced at the factory for smooth, vibration-free performance right out of the box.
• Solvent-free, water-based UV paint process - environmentally responsible with minimal energy consumption.
• Intelligent hub marking displays part number and minimum discard thickness for easy service reference.
• Includes all required mounting hardware for a complete, tool-ready installation.

Product Description

The Brembo 09.R103.11 is a PRIME UV Coated, internally vented front brake rotor engineered as a direct OE replacement for the Mercedes-Benz X164 GL-Class and selected W164 ML-Class and W251 R-Class models. At 350mm in diameter, it is the larger of the two front rotor sizes used on the W164/X164 platform, fitting GL450, GL550, GL320 CDI, GL350 BlueTEC, ML550, and 7-passenger R350 variants. It directly replaces Mercedes-Benz OE part numbers 1644210512 and 1644211412, ensuring a confirmed bolt-on fit without modification.

Built from high-carbon cast iron with an internally vented design, this rotor handles the thermal demands of heavy SUV braking effectively, resisting fade under sustained use. The full UV coating - applied using a solvent-free, low-energy process - protects the entire rotor surface including internal vents, providing corrosion resistance that exceeds OE standards. Each rotor is ECE R-90 certified and electronically balanced at the factory. Sold individually; two rotors are required to complete a front axle service.
