• ML320, ML350, ML550
• R320, R350, R500

Common Issues Addressed by This Rotor

• Brake pulsation or vibration due to warped rotors
• Reduced braking efficiency from worn or thin rotors
• Corrosion and rust buildup affecting rotor surface
• Overheating caused by insufficient rotor ventilation
• Uneven brake pad wear linked to rotor surface condition

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard limit of 1.16 inches (29.4 mm) to maintain safe braking performance. Use proper torque specifications for the 5 mounting bolts on the 4.41 inch (112 mm) bolt circle diameter. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for rotation direction. Check compatibility with your specific Mercedes-Benz model and year before installation.
