Product Details

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on corrosion resistance across the rotor’s exposed surfaces, including the disc and hat areas. For front brake service on the Ford Explorer and Mercury Mountaineer, this rotor uses a floating disc mounting design, a 3.228 in. center hole diameter, and straight vane venting to support heat management during repeated stops. The part number 320.65091F is a direct fit for the listed front applications and matches the specified dimensions for proper brake service.

Common Brake Issues This Rotor Can Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from rotor wear beyond discard thickness
• Surface corrosion on exposed rotor areas
• Noise or vibration related to rotor finish irregularities
• Heat buildup during repeated front brake use

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and wheel bolt pattern before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect pads, calipers, and hardware condition during brake service. After installation, follow the brake pad manufacturer’s bedding procedure to help establish even pad transfer on the new rotor. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Centric GCX rotors are engineered to meet the dimensional and finish requirements listed for the application, including the specified thickness, diameter, and coated surfaces. Part number 320.65091F is built for the confirmed front fitment on 2002-2005 Ford Explorer and 2002-2005 Mercury Mountaineer models.
