Brian, can you describe the steps you took to bleed the brakes? If you don't have a vacuum pump, it's a two man job.
Here's how I bled my CJ brakes before I bought a wonder tool called a "Mighty Vac" pump and gauge.
Do the breaks in the following order:
1. Passenger side Rear Wheel.
2. Driver side Rear Wheel.
3. Passenger side Front Wheel.
4. Drivers Side Front Wheel.
Steps to be taken on each of the above steps:
1. Open the bleeder screw and attach a clear line from the bleeder screw into a jar. You want to see what's coming out!
2. Top off the Master Cylinder.
3. Have a buddy slowly depress the brake pedal.
4. When the pedal reaches the floor close the bleeder screw.
5. Release the pedal.
6. Reopen the bleeder screw.
7. Reapply pressure to the brake pedal.
8. Continue steps 1-7 untill you see a constant flow of fluid with no air coming out of the bleeder screw.
When the Passenger Side Rear wheel line has been bled, do each of the other lines in turn. When no air is trapped in the lines you're done and the brakes should NOT be spongy, but firm when the pedal is depressed.
