Hi, I have a 93 wrangler 2.5l 5spd. My rear brakes are not working at all. I removed the drums and neither one of them move at all. They don't move when the parking brake is applied either. I blead the rear brakes and there is fluid coming from the lines but it didn't help the problem. Is it possible that both wheel cylinders are bad? There was alot of mud and crap in the brakes and i cleaned everything up good and spayed everything with wd40 hopeing it would loosen things up. Thanks in advance for any help.

Cleaning all the junk out is a good idea but be careful with the wd if you get it on the shoe surface it will ruin them.
Pulling the brakes apart and cleaning and lubing the pivot points would be better.
If the wheel cylinders are not leaking they should be fine unless the pistons are locked up and again pulling them apart and cleaning them could be a good idea.
Applying the parking brake and nothing moving is not good. Did the parking brake pedal move ?
