Detailed Description

DFC Geospec Rotors 4004-63045 are engineered as a direct-fit brake rotor set for select Mercedes-Benz GL-Class, ML-Class, and R-Class vehicles. This application coverage includes front and rear rotor replacement for models such as the Mercedes-Benz GL450, ML350, and R350, with notes for specific rotor sizes, vented rear rotors, and wheel requirements where applicable. If you are servicing a Mercedes-Benz GL350, ML550, or R320, this rotor set provides the correct fitment reference for those listed model years.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Reasons

• Brake pulsation from rotor wear or thickness variation
• Scoring, grooves, or heat checking on the braking surface
• Noise during braking caused by rotor condition
• Reduced braking consistency on Mercedes-Benz GL, ML, or R-Class vehicles
• Need for front and rear rotor replacement on the same service interval

Installation Notes

Verify rotor size, rear vented rotor requirement, and wheel fitment notes before installation. Confirm the vehicle year, model, and brake configuration against the listed applications for the Mercedes-Benz GL450, ML350, and R350 before ordering. Professional brake service procedures should be followed during installation.

DFC Geospec Rotors are part of Dynamite Friction’s brake component lineup and are cataloged for specific vehicle applications to support accurate replacement selection.
