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.
