Product Details

The DFC GEOSPEC rotor design uses G3000/G11H18 cast iron and OE-matched machining tolerances for durability and stability. Each rotor is inspected for critical dimensions, and vented rotors are balance-checked for consistent operation. The 5000 Advanced pads are formulated for stable friction performance and assembled with premium shims to support quieter stops. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Used For

• Rear brake service on Mercedes-Benz GLS450, GLS350d, GL350, GL450, and GL550 models
• Replacing worn rear rotors and pads that cause brake noise
• Addressing vibration, pulsation, or uneven braking feel
• Restoring braking response after rotor wear or pad fade
• Reducing rust buildup on exposed rotor surfaces
