Default Brake Bleeding

I am actually not a bad mechanic, just don't have a lot experience on brakes. I put in a tow new disc calipers and had to unhook the brake lines. I am having a real problem getting any pedal. I have bled them several times but am getting very little pedal. I start in the back rear passenger and get a lot of fluid out of that one, but the rest I don't. Do I need to just keep bleeding or is there something esle wrong. Been using a hand bleeding presure pump. Thanks for your help, any suggestions would be great.

keep bleeding. Some time it takes a lot of time. Make sure to keep the master cylinder full to prevent sucking air back into the lines.

I usually use a vacuum pump first and then do it the old fashioned 2 person way for a little while. It can take a while to get the air out. I also second keeping an eye on the MC to make sure it stays full and doesn't suck air.

Thanks all, I will keep at it. By the way I didn't tell you what I am working on 1966 Mustang GT.

What are you calling a hand bleeding pressure pump? Is it a cannister with brake fluid and a hand pump that fits on the reservoir?

I would love to have one of those that attatches to the master cylinder. I just use a hand held vacuum pump with a little catch jar at each wheel before doing it the old fashioned way.

I do it all with the foot pedal. If you use speed bleeders you don't even need another person to help. I use them on all the race cars, because @1am when I'm working on the cars I don't have the luxury of calling for help. Make sure everything is tight, keep the fluid topped off and keep going...

The speed bleeders are cool. I have used them before.

Motive Products makes an inexpensive pressure bleeder that is very similar to a bug sprayer. In fact I saw someone with one that they made from a bug sprayer. I would not bother with the bug sprayer since the Motive is only about fifty or sixty bucks.

The only reason I have a pressure bleeder is because I live in the boonies and I rarely have a helper handy now that my kids are grown and gone.

The speed bleeders are top notch, but you have to spend that fifty bucks or so for every car, vs. the Motive as a one time expense, plus a minimal cost for different adapters. An adapter covers a wide range of cars and trucks.

All that said, it's tough to beat a good old fashioned wife pumping the brake pedal type bleeding process.

ya. i'm n ot sure what you mean with handpressurepump. if bleding is done wrong you just suck in air from the back and never hget it finished (just making it worse).
if you are bleeding correctly, then do it in the right order. from longest line to shortest, which I tink is what you are doing.
What worries me a bit is that you say that you have pressure on one side in the back, but not in the other. The back is connected with a t-piece. So if you have pressure in the back it can't be more than a few pumps to have it on both sides as it's the same line.
Did you change anything in the back? if not, then I believe there's something wrong in the method you bleed.
can you give us info on what tool you're using?
