2nd Gen Non-Engine/Transmission Uneven rear brake shoe wear

[WAHarrison]

Just replaced the rear shoes on my 94 2WD, and noticed that the driver side shoes were only half gone, while the other side was down close to the rivets. I though that was strange but could not explain a cause for it, shoes looked glazed over, so I said that's what kept them from wearing out.



After the new shoes, I noticed that the right rear tire would slide in a hard stop, not good. So I said, I now have a leaking wheel cylinder. This is after about 1000 miles on new shoes. Removed right rear drum, and dry as a bone. Normal dust, and shoes looked very good, uniform contact on both.



Now I am perplexed as to why this side is locking up, and just for the fun of it, (not much fun to get the drum off) I pull the drum off the other side and the shoes look like I just put them on. The front shoe is not even getting out to the drum, and the back shoe is just barely worn.



It looks like uneven hydraulic pressure, but I have no way at present to measure that. Factory service manual is no help for this type of problem.



Any ideas??????

Are both automatic adjusters working properly?

When I removed the drums the first time, with the old shoes. Each set of shoes was just dragging on the drum when it came off, so the adjusters had the shoes up where they should be. I cleaned and checked everything when going back together.

Sticking wheel cylinder or a problem with a valve of some sort not releasing pressure when you let off the pedal maybe?
