An apparatus and method for removing and flushing hydraulic fluid and contaminants from a vehicle's or other equipment's hydraulic system, and refilling the hydraulic system with new fluid. The apparatus has a vacuum pump to remove old hydraulic fluid from the master cylinder (reservoir) and a manifold and hose system to allow all bleeder valves and the ABS valves to be vacuumed at the same time through a hose system to a waste fluid container in the apparatus, a reversing vacuum pump to transfer waste fluid from the waste fluid container in the apparatus to an exterior storage tank, a reversing fill pump to pump new fluid from the new fluid container (in the apparatus) to the universal master cylinder adapter which connects the fill hose to the master cylinder, a combination of surging fill flow and surging vacuum out flow to produce a safe rapid removal of old fluid and refill of new fluid, a cross venting system to keep moisture and other contaminants from entering the new fluid container and to keep either the new fluid or the waste fluid container from venting fumes to the atmosphere. The apparatus also has sensors to detect and correct pressures and vacuum for safety and pump life. The apparatus also has a sensor to detect fluid levels in the waste fluid container in the apparatus, and a sensor to detect the availability of new fluid available for the service. The apparatus also provides a monitored leak containment area in the bottom of the apparatus to contain any leaks and advise the service provider of a leaking condition. The vacuum pump and vacuum wand can be used to clean out the containment area.

[ What is claimed:] [1.]1. An apparatus for removing and replacing hydraulic fluid used in a hydraulic system, comprising:a cabinet;a leak containment tank under the cabinet to contain leaks from within the apparatus;a computer control unit;a new fluid container in said cabinet for providing a source of new fluid for use in flushing and filling the hydraulic system;a waste fluid container in said cabinet for receiving waste fluid from the hydraulic system;a reversible fill pump in fluid communication with the new fluid container and controlled by the computer control unit for dispensing new fluid from the new fluid container to the hydraulic system through a fill hose to be connected to the hydraulic system;a reversible vacuum pump in fluid communication with the waste fluid container and controlled by the computer control unit for vacuuming waste fluid from the hydraulic system to said waste fluid container through one or more bleeder valve hoses to be connected to the hydraulic system and said waste fluid container;a connection means at an end of each of said one or more bleeder valve hoses;a connection means at the end of said fill hose; and,a vacuum wand connected with a first end of a vacuum hose, the reversible vacuum pump in fluid communication with the other end of the vacuum hose for vacuuming fluid through the vacuum wand.
