Bill G and others, Getting the Drum off is my current issue to see what I have. What should be the slot to allow for loosing the adjuster has a steel plug/plate on the inside.
I have never heard of a steel plate on the inside covering the adjusting slots. I guess once you get the drum off, you'll know what that is. They usually have rubber plugs that push in from the outside, and often those are missing. Are the 2 slots you see at the bottom of the backing plate? As far as loosening the adjuster, you use one screwdriver to push the spring lock away from the teeth and use the other screwdriver (or brake lever) to push the toothed wheel up (inner side). That direction should be true for left and right since both adjusters flick the wheel up on the outer side, so you want to turn it the opposite direction to loosen. If the slots can't be opened, perhaps you can pull the drum out enough to slip levers between the shoes and backing plate to get at the adjuster. It is on the bottom, in the middle. You can find photos here if you search.
