Ok all adjuster bolts turn but only 1/4 of adjusters inside drum are free and don’t want to break bolts off

One wheel freed up but the wheel that I can’t spin by hand both are stuck

Spraying down but I doubt fluid is getting to where it needs to

Suggestions to get drum off without ruining

Only thing on the back I could release is wheel cylinder

BTW what an excellent idea for adjusting brakes instead of those horrible slots
