98 Chrylser Cirrus(Dodge Stratus look alike) rear brake problem

Hello all. New to the forum. I have a 98 Chrysler Cirrus that has a
problem with the rear passenger side brakes.

3 times now, I have replaced the wheel cylinder, brake shoes, springs, and
the drum, and 4 times now(yeah, it's burnt up again) it has burnt
completely up because of a shoe that is dragging against the drum
constantly and building up heat and then destroying everything inside of
the drum. Everything was put back new each time except for the brake
adjuster, which all the local autoparts stores tell me they cannot order.

I know it was put back together correctly because if you've ever seen this
particular set of shoes, they only fit one way. And the left driver's side
has given me no problems at all, and I was the one that did the work on it
when I changed it all as well. It got a new drum, shoes, and springs
only, no wheel cylinder was necessary.

It's also been suggested that the rubber hose that connects to the metal
tubing that goes to the wheel cylinder may be clogged or is collapsing and
not letting fluid flow backwards out of the wheel cylinder when the brake
is released. I have not changed it yet either. But I did feel of the
hose, for whatever good that will do, and it did not feel weak and did not
collapse under my squeezing pressure. Visibly, it looks fine.

Has anybody ever had this happen, and what do you do about it?? Change
hose?? Try to get a new adjuster from a dealer or a junkyard??

Thanks for any replies.
