Yep - this helps, so I did adjust the rears. Problem is, the pedal is still
mushy and the rear brakes are so tight they are now dragging. Bulging hoses
would not "pump up" would they? I would think that they would swell and
then shrink with each successive pedal pump. The symptom I am getting is
that the brakes will pressurize after the first pump.
I am wondering if it might be the master cylinder...??? If the seals were
bad, it would act like this, right?

I only do one side at a time for exactly this sort of reason! :-) Even if
they were on the wrong side, I bleed the brakes with an EZBleed and attach
the drain hose to ball-type check valve submersed in brake fluid.

At 4-6mm it is time to replace your rears anyway. No special tools are
needed, just patience. Do one side at a time so you have the other for
reference. Have the drum turned too if there is any scoring or a ridge
on the outer edge.
