87 4Runner Brakes very spongy

I have an 87 4Runner that I knew had bad rear brakes, but the vehicle
still did well at stopping quickly. After removing the drums, I
decided to replace the rear cylinders, one brake line, pads and
drums. After everything was back together, I went through and snugged
up the lines, adjusted the emergency brake until it was tight and bled
the brakes starting with the furthest from the Master Cylinder (which
is also new within the past 5 months) and ending with the drivers
front brake cylinder. THe brakes still seemed very spongy and I was
unable to lock the brakes up onmy gravel driveway and the vehicle took
a greater distance to come to a stop than it should have, so I went
ahead repeated the bleeding process after making sure that there were
no leaks and the lines were nice and tight. Needless to say I have
bled the brakes a total of 6 times and there is still no luck. The
front brakes and calipers are around a year old with maybe 10,000
miles on them. It doesn't make much sense that the brakes worked
better before the new rear brakes than they do after all new rear
components. Anyone out there have any ideas? Any help would be
greatly appreciated.

This will sound stupid but it might just work. Try bleeding with the
rear of the truck jacked up as high as possible. Then try bleeding
with the front jacked up. If there is air in some hard to reach place
that might move it to where you can expel it. This technique is
really for bleeding cooling systems and not hydraulic systems but
you've tried everything else. Just a thought. Good luck. Al
