So I put new u-joints and pads on the front of my YJ back in Jan. After that I have a real soft pedal and comes to a slow stop. My brakes were not very good before that, but they really don't work good now. Since this happened I have changed the pro-valve, rotors, master cyl, pads, and bled about 20 times. Yes my bleeders are above the line. 2 years ago I replaced pads, rubber and metal lines, and MC. Somebody told me it's possible for rubber line the get a bulge in it when you hit the brakes and cause this, I don't think that's the problem.
I am not sure what you mean by your bleeders are above the line. A common mistake and I have done it myself is to buy two of the same calipers or to mix the calipers on the wrong wheel.
Look at your calipers and see if the bleeder is on top with both calipers.
Another thing to look at is the caliper rubber hose. Have someone push on the brakes with the motor running and you hold onto the rubber lines. Have the person inside pump the brakes slowly and hard for you to check and see if the rubber lines are expanding.

If that doesn't work it could be your booster. I had the same problem. If it is don't buy a reman. I highly suggest doing a TJ booster/master swap or if you can find a 95 6cyl booster. You will be amazed at the difference. It's like a whole new vehicle.
And (just to double check) rear brake pads put on correctly - 1 is for front & 1 is for the rear.
(Is it Longer on front side of the drum & shorter on R. side?) Been a few months since I rebuilt mine...
Put on new booster and didn't fix it, then new shoes and drums. I got stronger brakes, but still wont lock up. It kinda like there's not enough brake pressure to stop the wait of the Jeep. I ordered new front hoses today.
I had the same problem with my new jeep, i replaced everything and it ended up just being my bleeder screws were clogged. Not sure how that happened or ever even heard of that happening but just a thing to check just incase!
A bad booster wouldn't cause soft brakes (you already figured that out)
If you are positive you got rid of all the air I would bet you have some questionable rubber hoses in your brake system. They only have to expand a tiny bit to make the brakes soft.
My pedal gets soft to tell me its time to adjust the rear brakes. Not replace them just adjust them. Most of your pedal travel comes from the rear brakes so I would check them first and go over them very well. Also there is a chance there is a bad seal in the MC. Can you pump up the brakes to temorarily get a stiffer pedal? (There are alot of jokes in there but since this is family friendly I will leave you to find them on your own)
