The DFC rear-upper brake hose for 2009–2010 Ford F-150 4WD applications is a vehicle-specific hydraulic line intended to replace the factory rear-upper hose and maintain proper fluid transfer to the rear assembly. Suited for routine brake system repair or replacement when the original part shows wear or leakage, this hose matches the F-150 4WD rear-upper fitment for those model years to simplify installation.
