ABSTRACT:
A brake fluid flush machine to simultaneously supply fresh brake fluid and vacuum used brake fluid in a vehicle's braking system while being controlled by a processor to allow a single worker to complete the fluid exchange operation. The machine has 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 controls the fluid exchange by sequentially opening and closing valves that couple the four secondary brake cylinders with the suction pump.
