Rear Disc Brake Kit for Ford and Mercury SUVs

The Dynamite Friction DFC GEOSPEC Coated Rotor- 1400 Ultimate Duty Performance Pad disc brake kit is built for rear brake service on select Ford and Mercury applications. Part number 4402-54040 covers direct-fit rear brake replacement for 2006-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, and 2006-2010 Mercury Mountaineer.

  • Rear disc brake kit for service replacement
  • DFC GEOSPEC coated rotor for corrosion resistance on exposed surfaces

Product Line Details

The DFC GEOSPEC coated rotor line is focused on rotor protection where the hat and non-friction surfaces are exposed to moisture and road debris. Paired with 1400 Ultimate Duty Performance Pads, this kit supports rear brake refresh work on the Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer without requiring you to piece together separate rotor and pad components.
