I cheat because it's a better, easier way to change brake fluid. Purchase a 12 volt fuel pump, Low pressure pump that does 10 psi or less will work fine. Purchase some clear poly tubing, the semi soft kind, that will fit over the brake bleeder nicely. Connect that line to the 12v fuel pump intake port, connect some more of same line to the output side of pump. Place output hose in an empty soda bottle.
Open brake master cap. Open bleed valve [Start at the longest line]. Have supply of fresh fluid handy. Turn on pump and watch the master cylinder reservoir level go down. When the reservoir level gets to bottom 1/4 , add clean fluid and pump more while watching for clean fluid to come out of bleed port. When you get clean fluid, stop the pump and close the bleed port. Refill the master and move to the next longest line. Repeat for each wheel, always keeping the master reservoir with a good supply of clean fluid. Total time to bleed all 4 wheels and replace the total fluid with fresh is usually less than 15 minutes. It helps if all 4 wheels are off the ground and car in firmly on jack stands. As always, be safe. 12 volt, low end fuel pump online cost was less than $25. That pump is a dedicated brake bleed pump only now. When I'm all done, I flush the pump with mineral spirits [cheap paint thinner available at any hardware]. Dispose of the used brake fluid properly.. save the baby seals and the whales.. as always.
