Now that I've torn it down, I can do it again next time BEFORE it becomes a problem. If we go on another epic ride, I'll just pull the drum and clean everything up as a preventative measure. When the shit ain't seized up, it's easy on and off.
Now here's the kicker - I ordered a batch of parts from the dealer - shoes, some o rings, seals, snap rings, etc.
$134 total.
(Fixed the $450 back plate with JB Weld equivalent from Autozone.)
Went to pick the parts up, identified myself, and they handed me a box.
Didn't offer to go thru it line by line, and I didn't feel like messing with them, I was in a hurry, so I just took the chance.
Well, turns out they didn't include the snap rings and 1 o-ring I needed.
Not a big deal money wise, I had an O ring in my plumbing kit that I subbed, and Tractor Supply had snap rings for $0.99.
But the fact that I had to spend time and go hunt those down pissed me off a little, so I'm just gonna keep the 3 extra complete sets of brake shoes that they included in my box. Slugger has shoes for life now.
I'll be going to Harbor Freight after work and buying an assortment of snap rings and O-rings for the shelf.
I love it when I need something and have it already.
