Abstract: A fluid exchange machine for removing used transmission fluid from a vehicle's cooling system and replacing the used fluid with fresh fluid includes a fresh fluid tank, a used fluid tank, a pump for forcing fresh fluid from the fresh fluid tank to a vehicle's cooling system, a processor for controlling a fluid exchange operation, and a display coupled to said processor for graphically representing a status of the fluid exchange operation. The display can be an LCD display or other display capable of graphical representation of the conditions and status of the fluid exchange operation.

Abstract: A brake fluid flush machine comprises a used fluid tank, a new fluid tank, a manifold connectable to four secondary brake cylinders, 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 valves may be opened according to a user specified sequence.

Abstract: 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.
