Shimano is pretty simple, fill a syringe with new fluid (inert mineral oil), attach to the bleed screw on the caliper, then thread a cup onto the lever. Open the bleed screw, and push the new fluid through. It'll flush the old fluid up into the cup and bleed the system at the same time. Shimano calls it "one way bleed."
