Detailed Product Description

This Beck Arnley disc brake rotor (part number 083-2973) features a vented construction that helps reduce heat buildup during braking, which is critical for maintaining consistent stopping power and preventing brake fade. The rotor is designed with a 5-lug configuration and a 112 mm bolt pattern, matching the specifications required for select Mercedes-Benz ML series vehicles. With an outer diameter of 345.8 mm and a rotor height of 51 mm, this rotor fits precisely to ensure optimal contact with brake pads.

The rotor hub outer diameter measures 169 mm, and the rotor ID is 156 mm, providing a secure and stable mounting surface. The lug stud hole inner diameter is 15.4 mm, accommodating the vehicle’s lug studs accurately. The rotor surface thickness of 32 mm and a minimum thickness of 30 mm ensure the rotor maintains structural integrity and performance over time. This rotor is not solid but vented, which enhances cooling efficiency during heavy braking.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz ML55 AMG, ML430, and ML500
• Addresses brake fade caused by excessive heat buildup
• Improves braking consistency and pedal feel
• Restores proper rotor thickness for safe braking performance
• Eliminates vibrations and noise associated with damaged rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt pattern and lug quantity match your vehicle’s specifications. It is recommended to replace brake pads simultaneously to optimize braking performance. Check rotor thickness with a micrometer to confirm it meets or exceeds the minimum thickness of 30 mm. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.
