If you don't have the opposite wheel on the ground or otherwise kept from turning you won't get a sticky wheel/drum on the other side to turn under power, that's how the differential works, this is normal. If this is the situation put that wheel back on and set it down, again try to get your sticky one to turn.
Unbolting wheel cylinders sometimes helps free things up but usually not a lot in my experience.
The brake adjusters are same each side. Just the Budd lug nuts/studs that are left and right hand thread.
