Detailed Product Description

This disc brake rotor from Dynamite Friction is part of the DFC Hi-Carbon Alloy GEOMET Coated Rotor line, which combines high-carbon alloy material with a GEOMET coating to improve corrosion resistance and rotor longevity. The vented design allows for better heat management, reducing the risk of brake fade during extended use. With a nominal thickness of 32 mm and a discard thickness of 29.4 mm, this rotor maintains structural integrity throughout its service life. The precise bolt hole diameter and quantity ensure a secure fit on Mercedes-Benz GL350, GL450, GLE400, GLS350d, and GLS450 models, making it a reliable replacement part.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading corroded rotors to improve braking consistency
• Addressing excessive brake noise due to rotor surface irregularities
• Restoring proper rotor thickness to maintain braking efficiency
• Ensuring compatibility with Mercedes-Benz GL and GLE series vehicles

Installation Notes and Tips

When installing the 900-63146 rotor, verify that the rotor thickness is within the specified discard limits before installation. Ensure the mounting surface and bolt holes are clean and free of debris to prevent misalignment. Use proper torque specifications for the five 15.3 mm bolt holes to secure the rotor firmly. It is recommended to inspect brake pads and other related components during rotor replacement to maintain optimal braking performance.
