Cj Spongee brakes

THe run down:

4 wheel disks using a ford (big) bronco/f100 hubs, spindles and rotors on all 4 corners (5 by 5.5 bolt pattern)

69 corvette master cylinder no proportioning valve yet

front calipers are from a 2wd C10 (long hoses) using the factory 4x4 (chevy) backing plates.

Rear calipers are 4wd front c10 calipers (short hoses) using the Chevy front 4x4 backing plates.

Question is: is the rear calipers requiring too much volume to work? THe 4x4 caliper piston is larger than the 2wd.

How do I fix? I was going to start by getting the same calipers on the front and back. What would be a good setup for me? Keeping the front setup and maybe changing the rear calipers and ? master cylinder?

I have tried bleeding these brakes so many times with gallons of brake fluid at very joint and no improvement.

Bleeders on top of the calipers? It's very easy to switch calipers side to side and not realize it. They will never bleed right if you do this.

yes bleeders on top.

The front brakes seem to work correctly. in 2wd low I cannot hold the rear wheels from spinning at idle no matter how hard i hit the brakes and how many time I pump them. That is why I was wondering about the volume required. I know calipers mainly rely on pressure not volume but maybe the piston size is too large? What about using residual pressure valves?

I have been running this setup for a while with soft pedal and am just tired of it. I sometime have to put it neutral (automatic trans) in order to stop. I am getting too old to live on the edge of disaster anymore. Plus my son just turned 18 and want to give it to him.

Is the rubber seal under the cap swollen?
