    Folks, I gave up after struggling with one side of the drums this afternoon. I was attempting to remove the drum from the driver's side rear, as I hope to take this vehicle on a rather long trip soon, and would like to inspect the brakes before we leave. I'm not sure which way to turn the star wheel, and after messing with it for a couple of hours, just put the wheel back on.
    What am I missing? I had hoped that the drum would rather easily slip off, but no go. I am not sure which way to turn the star adjuster, and was wondering if anyone had any suggestions for removing those pesky rear drums.

    Thanks so much in advance!

    Next time you try moving the adjuster move it just a little and check the drum to see if it still rotates freely. Keep checking for free movement on the drum, if it locks up you are going the wrong way.

    When you figure out the correct direction to turn the adjuster you may find it easier to slip a small flat bladed screwdriver in beside the adjusting tool and pushing against the ebrake lever inside.

    They have a tendency to get caught on the adjuster wheel and you way think you are doing something when in reality you aren’t.

    For the life of me I can never remember which way they go myself and I’ve probably done hundred, or more.

    Oh ya, sometimes its not the brake shoe that is holding the drum in place but rust around the center hub where the drum contacts it. Spray some penetrating oil, PB blaster is my favorite. Then tap the drum around the center hub a few times before trying to remove it again.
