Ever had self adjusting brakes overtighten?

Brakes were tight about 3 days ago after I let the self adjusters do their thing. I just pulled car into garage and let it sit ‘till yesterday. I jacked it up yesterday and both wheels turned nicely - felt perfect. Very light drag...stopped turning after about one revolution when I spun them. I exercised the E-brake several times and it fully released each time. I pumped the brakes several times and checked the rear wheels...no change... they seemed to turn freely. Sure is looking like fluid is having trouble getting out of brake cylinders and causing drag when the system is warmed up - but not happening when cold. I now have a new set of rear brake shoes, new flexible rear brake line, and Permatex lube coming soon (per suggestion earlier from RustyRatRod. I think I’ll go ahead and install the new master brake cylinder and make sure I blow compressed air thru lines to see if they seem to be clear. Will also try checking E-brake cable to make sure it’s moving freely. (Reminder... just replaced the rear wheel cylinders). I also have new brake springs coming...maybe new spring config won’t bind against the wheel cylinder like the current one does.
