Well you know, first you have to pass the brake mechanix coordination test.... Stand with your feet shoulder width apart. Next bend over to hands on the ground and your on all fours. Then kick your right leg out..... Next bark...... Got that far? Yup you pass. --Ok its silly but just to say its ez. 😁
All kidding aside, go buy speed bleeders and replace the stockers. It make it waaaaay easier on the bleed and generally you can skip needing a pump. Also go steal your wife turkey baster, It's used to suck all the fluid out of the reservoirs. Do that first and clean the shit outta each, paper towel the inside, then hit the nasty corners with Qtips. Clean! Clean! Clean!
Then go from there and refill. You can now just pump clean fluid thru to the new speedbleeders, a little at a time, of course with plastic hose attached. (think Lowes, cheap). Another cheapo step could be with a punched hole in a jam jar, with the plastic hose fed in, so you can watch for bubbles. - (I have the Mityvac plastic containers)
You can feeeeel when you are pumping good fluid and tighten up the speed bleeders. Its simple, but very basic is what you need.
