    Got the brakes unstuck.
    @LameMule that is pretty much what I’ve done, sir. The shoes released then.

    I know you got them broke lose but just some info for the thread. Even with the 30/30’s caged the shoes can still rust to the drum if the environment is right. The gap between shoe and drum isn’t that large when caged and if the drum has a wear lip on it it can still be making slight contact with shoe. Rust and dust blown in there while sitting will build up and bridge the gap.

    That’s what I believe happened to mine. The shortened cage bolts didn’t expand the shoes far enough and from sitting for 4+ years the shoes seized on regardless.

    Glad you got it. Had to laugh, those dust guards went missing all the time.

    Here is another question. Now that I moved the truck. Should I leave the brakes caged or cage them?
    It will be a minute before I will find a transmission and engine for it. So I’m not sure if I should un-cage them meanwhile?

    If you want to let the springs relax back into their normal state and still want to be able to move the truck around. Uncage them and then back the adjustment on the slack adjusters all the way off. This will actually pull the shoes farther away from the drum then caging the spring will. Everything will be relaxed that way. When time to get truck drivable again just readjust the slacks and grease ‘em up.

    After sitting for over 4 years already, and still more sitting in store, I would leave them caged and replace all 4 chambers whenever the truck is back together.
    That’s the logic in my answer above.
