Durable Construction and Precise Fitment

The DuraGo BR900876 rotor is constructed from cast iron, a material known for its ability to withstand high temperatures and resist warping under stress. Its full cast, solid design ensures structural integrity and reliable braking response. With an outside diameter of 12.99 inches and a nominal thickness of 0.55 inches, this rotor is engineered to meet the exact specifications required for Mercedes-Benz ML320, ML350, ML450, ML500, R320, R350, and R500 models. The drum-in-hat design integrates a rear drum brake surface, making it suitable for vehicles equipped with this braking system. The rotor does not include an ABS tone ring and features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.

Compatible Mercedes-Benz Models and Applications

This disc brake rotor is compatible with the following Mercedes-Benz vehicles:

• ML320
• ML350
• ML450
• ML500
• R320
• R350
• R500

It is designed to replace worn or damaged rotors, restoring braking efficiency and safety for these specific models.

Common Issues Addressed by DuraGo BR900876 Rotor

• Brake pulsation caused by warped rotors
• Reduced braking performance due to worn rotor thickness
• Noise and vibration from uneven rotor surfaces
• Brake fade from overheating during extended use
• Corrosion-related rotor damage (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

When installing the DuraGo BR900876 rotor, ensure the mounting surface is clean and free of debris to prevent uneven rotor seating. Verify the rotor thickness before installation; replace if below the discard thickness of 0.45 inches (11.4 mm). Since this rotor is non-directional, it can be installed on either side without affecting performance. Use proper torque specifications for the 5 mounting bolts to secure the rotor firmly. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system function.
