The DFC brake wheel cylinder fits 1964–1967 Buick SportWagon front left applications, providing the hydraulic actuation at the wheel for that drum brake location. Intended as a replacement when the factory cylinder leaks or binds, it helps restore proper shoe movement and braking response. Install during wheel-end brake service to return reliable hydraulic operation at the front left wheel.
