rear brakes on a 99 Taurus sticking

my g/f has a 99 taurus and when she goes to brake, the right rear wheel locks up and slides. I took the drums apart and didn’t see anything wrong on either side. plenty of meat on the shoes, and when the pedal is depressed you can’t turn either wheel.

any suggestions on what’s causing it to stick?

It could be the adjuster ( the threads get rusted and it doesn’t adjust) You could try backing the adjust off a bit. That’ll also let u know if its rusted up. Drum brakes suck…sooooo many moving parts, springs, levers, ect.

i’ll try that tomorrow in the morning then, i checked it before and it didn’t look bad at all. but i didn’t adjust it at all.
