what kinda car is this?and did you try the "gravity" approach?
Fill the master cylinder up,crack open the right rear bleeder,put a catch pan under it,and let gravity take its corse,make cure the master cyl is full,and yes it sounds dumb,but it works, try first to pressure blead them all one by one,starting in right rear,to left rear,then right front to left front,
theres probally alot of air in it,but the gravity bleed should work.. it just takes time,like a hour or 2,try it and respond
