    No way to spray anything on the shoes or drum. The shields effectively block that.

    Even though the slack moves, I did back it all the way to see what would happen. Nothing.

    Both wheels came off, then the brake drum. Was able to use a crow bar to pry the s cam into the proper position. Luckily the bushings are fine. Drum was pretty rusted so used some sandpaper to take some of it off. Just a light scuff.

    If the cam is what was frozen, I would pull it and clean it up good and install new bushings, less than 20 bucks for both sides. If you unbolt the cam tube from the back side of the spider, you can do this without pulling the hub, so will not need a new seal.

    Not sure if this will help in future, but I have run straight 120 psi directly to the air can itself before in one obnoxious case,


    outside of that, I generally just leave truck on for an hour or so with brakes released and smack em every few minutes, that one even did the trick on a trailer that had sat for 3 years after being parked in a salty winter spray, I was quite surprised
