I've managed to bleed the back brakes but I can't get the front brakes to bleed. They suck the air in, even while i'm using a one-man bleeder kit. I double checked the backs..... 0 air. Does anyone know what I might be doing wrong???

Sounds like a faulty bleeder, but also I have heard that the one man bleeders can be a pain to use on new lines that have no fluid in them because there is no fluid in the line that will allow the air to be pushed out. So what happens is the spring end on the bleeder hangs open sucking air back up in the line.
Not sure if I explained that correctly. I would gravity feed the fluid until it gets to the bleeder end then install the one man bleeder and finish up the job.

I flushed and blead the brakes with a power bleeder and at times I had problems with air coming out, it would bleed clean and then a long stream of bubbles then clean again over and over, after six quarts of fluid I said hell with it, brakes work fine, the only thing I can think of is that it was sucking air through the bleeder threads and back out
the end of the bleeder?

I recently put four new calipers, new booster and new master cylinder, I can't tell you how important it is to have all the air out of the master. If you need to re-bencj bleed it, you can do so where the brake lines come into the master, you will need some one to slowly pump and hold the pedal while you loosen and tighten the brake line. Since there is no bleed screw there, have a rag handy to keep fluid off of your paint. Also, make sure you give the system time to get fluid into the lines (gravity bleed works well), it is a real pain in the butt to bleed out the brake lines and calipers otherwise. Good luck.
