The brake hardware is not in terrible condition, but it's all pretty rusty. I marred the adjuster nut a little trying to get it off (it was really frozen). Tomorrow it all goes into the ultrasonic cleaner, and we'll see what comes out. Regardless of how it looks, I am inclined to change out all the springs, adjusters - I already have new kits on the way.
The wheel cylinder is pretty rusty. I find it hard to believe it moves very freely, though this brake did seem to work better than the left side. Unlike the left, I didn't see any seepage under the seal. I'll replace it anyway.
