i used a one man setup before where there was a special container that you inverted over the reservoir to keep a steady supply. it was very simple - a bottle with a tube at the end going through a clear plastic plate. when you inverted it into the reservoir, atmospheric pressure kept the balance and it would fill automatically if the reservoir level went down. there was also some special arrangement with the collection tube and bottle so that no air would be introduced. you pumped the brake until the new fluid showed in the outlet tube. i think they have a kit like that at napa stores...
