The DFC brake master cylinder for 1969–1970 Buick Riviera is a direct-replacement unit that restores the hydraulic function of the vehicle’s braking system by controlling brake fluid pressure. It fits Riviera models from 1969 through 1970 and offers a factory-style swap designed to help reestablish predictable pedal feel and consistent braking performance for the era’s stock brake systems.
