Brake flare nut size?
Speed bleeders don't help cracking open a line to find where it's blocked 
I have a vacuum bleeder for one-man bleeding; works pretty darn good.
(Hazard Fraught sells one such, https://www.harborfreight.com/brake-...der-92924.html . I bought mine off Amazon, but as far as I can tell, it's the exact same unit.)

Got the exact same unit. Works well especially for changing the fluid....... BTW that is the one that would NOT pull the air out of the run to my rear brakes. I know its hard to believe, but it wouldnt, yet the method I mentioned worked...
Good luck.
