Technical Description and Specifications

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. With a nominal thickness of 32 mm and a discard thickness of 29.4 mm, it provides a clear service limit for safe operation. The rotor measures 350 mm in outside diameter and 67 mm inside diameter, fitting securely with five bolt holes each 15.3 mm in diameter. The rotor height of 54.9 mm ensures compatibility with the brake caliper assembly on compatible Mercedes-Benz models.

Compatible Vehicles and Applications

• Mercedes-Benz GL350
• Mercedes-Benz GL450
• Mercedes-Benz GLE400
• Mercedes-Benz GLS350d
• Mercedes-Benz GLS450

This rotor is designed specifically for these models, providing a direct replacement that meets factory specifications.

Common Issues Addressed by This Rotor

• Brake rotor warping due to heat buildup
• Reduced braking efficiency from worn or thin rotors
• Corrosion and rust on rotor surfaces
• Brake noise caused by uneven rotor wear
• Vibration or pulsation during braking

Installation Notes and Tips

Ensure the rotor is installed on a clean, debris-free hub surface to prevent runout. Verify the bolt hole alignment matches the vehicle’s hub pattern. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Torque bolts to manufacturer specifications and check rotor thickness regularly to avoid discarding below 29.4 mm.
