The DFC brake hose for 1974–1980 Mazda RX-4 (rear) is a direct-replacement flexible hydraulic line that connects the hard brake line to the rear brake unit. It restores necessary hydraulic routing to preserve pedal feel and prevent fluid leakage. Intended as a like-for-like replacement, confirm rear positioning for correct fit on the RX-4 across the listed years.
