Apparatus and method for removing and replacing vehicle hydraulic fluid

An apparatus for removing and replacing hydraulic fluid used in a hydraulic fluid system in a vehicle, comprising:

• a housing;
• a fresh fluid tank in said housing for storing a source of fresh hydraulic fluid for use in the vehicle;
• a waste fluid tank in said housing for receiving and storing a source of waste hydraulic fluid received from the vehicle;
• a fill pump for dispensing hydraulic fluid from said source of fresh hydraulic fluid to the hydraulic fluid system in the vehicle through a fill hose interconnecting said fresh fluid tank and the hydraulic fluid system;
• an adapter disposed between said fill hose and the hydraulic fluid system for removably connecting said fill hose to the hydraulic fluid system;
• a vacuum pump for suctioning hydraulic fluid from the hydraulic fluid system of the vehicle to said waste fluid tank through one or more bleeder valve hoses interconnecting the hydraulic fluid system and said waste fluid tank;
• connections means at an end of each of said one or more bleeder valve hoses for removably connecting each of said one or more bleeder valve hoses to a bleeder valve on the vehicle;
• and
• a suction hose connected to said suction pump for suctioning hydraulic fluid from a vehicle brake master cylinder in the hydraulic fluid system of the vehicle to said waste fluid tank.

A method of using an apparatus for removing and replacing hydraulic fluid used in a hydraulic fluid system in a vehicle, comprising the steps of:

• removing a cover from a vehicle brake master cylinder in the vehicle;
• activating a vacuum pump to suction out hydraulic fluid from said vehicle brake master cylinder to a waste fluid tank using a suction hose connected to said waste fluid tank;
• installing an adapter on said vehicle brake master cylinder, said adapter connected to a fill hose, said fill hose connected to a fresh fluid tank having a source of fresh hydraulic fluid for use in the vehicle;
• activating a fill pump disposed between said fresh fluid tank and said fluid storage reservoir to fill said vehicle brake master cylinder with hydraulic fluid;
• connecting a bleeder valve hose to a bleeder valve on the vehicle;
• activating said vacuum pump to suction out hydraulic fluid from the hydraulic fluid system of the vehicle to said waste fluid tank;
• disconnecting said bleeder valve hose from said bleeder valve and deactivating said vacuum pump;
• and
• deactivating said fill pump and removing said adapter from said vehicle brake master cylinder.

• an adapter disposed between said fill hose and the hydraulic fluid system for removably connecting said fill hose to the hydraulic fluid system, said adapter having a vent for preventing air-lock in said hydraulic fluid storage reservoir, said vent configured to allow air to escape from said storage reservoir during dispensing of hydraulic fluid to the hydraulic fluid system;
• a vacuum pump for suctioning hydraulic fluid from the hydraulic fluid system of the vehicle to said waste fluid tank through one or more bleeder valve hoses interconnecting the hydraulic fluid system and said waste fluid tank;
• and
• connection means at an end of each of said one or more bleeder valve hoses for removably connecting said one or more bleeder valve hoses to the hydraulic fluid system of the vehicle.
