Sounds like you need to check the flex hoses, remove the line at just before flex hose, does fluid come out now? If yes replace the hoses, Next remove the bleeder from the caliper, does it flow good now? If yes replace bleeder(clogged with dirt).

really bench bleed master, or open bleeders on front and allow them to gravity bleed. Don't let master go empty!
