A brake fluid flush machine is adapted to simultaneously supply fresh brake fluid and vacuum used brake fluid in a vehicles braking system while controlled by a processor to allow a single worker to complete the fluid exchange operation. The automatic brake fluid exchange machine comprises a used fluid tank, a new fluid tank, a manifold connectable to four secondary brake cylinders corresponding to a front driver's side wheel, a front passenger's side wheel, a rear driver's side wheel, and a rear passenger's side wheel, a suction pump connecting the manifold to said used fluid tank for draining used brake fluid from said four secondary brake cylinders, a pressure pump connecting the new fluid tank to the master cylinder, and a processor. The processor is configured to control the fluid exchange by sequentially opening and closing valves that couple the four secondary brake cylinders with the suction pump, where the valve connected to the rear passenger's side cylinder is first opened and then closed, followed by opening and closing of the valve connected to the rear driver's side cylinder, followed by the opening and closing of the valve connected to the front passenger's side cylinder, and then opening and closing of the valve connected to the front driver's side cylinder.
