The DFC brake wheel cylinder fits 1985–1991 Buick Skyhawk rear applications, delivering hydraulic actuation for the rear drum brake. Intended as a replacement when the factory cylinder leaks or sticks, it helps restore correct shoe movement and braking balance. Use during routine drum brake maintenance to return reliable hydraulic pressure and predictable stopping at the affected wheel.
