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.
