was hanging up the adjuster wheel when you tried to loosen it to get the brake drum off. (The left side did not do this). I had to poke a screwdriver in against the self adjuster and bend it out of the way. Once the wheel was off, I removed it and bent it back. To loosen either adjuster turn the wheel up. To tighten rear brakes, turn the adjuster down.
The adjuster has that screw that moves out when the adjuster turns. This screw pushes against the cylinder and the shoe. as the wheel turns, it unscrews the bolt, forcing the nut away from the wheel cylinder, moving the shoes towards the drum.
