The DFC rear up-position brake hose for 2017–2020 Ford F-150 4WD is a replacement flexible hydraulic line that restores brake fluid flow to the rear brake assembly. Supplied to align with the specified F-150 4WD routing, it preserves the flexible connection between rigid brake lines and the rear caliper or wheel cylinder so the suspension can articulate without interrupting hydraulic braking.
