When I first brought the bike home, the rear brake was completely stuck. The Previous owner drained all fluid from the reservoir, and took the bleeder out of the caliper. That's about it. He neither investigated further, nor attempted to fix the issue.
A week after I ordered two rebuilt kits the parts finally came, and I was able to get to the bottom of it. I started on the rear brake, as that was the one in the worst shape.
This is what 30 year old brakes hide under the dust seals
With the master cylinder rebuilt, I was able to use the hydraulic force to push the stuck piston out of the caliper. Except a hardened seal and some decent corrosion inside, the caliper looks good and can be reused. the piston, however, has some decent-size pitting. I'll have to look for a replacement.
Tomorrow I'll tackle the front.

Nice work! I was into the brakes of my bike today too. Do you have a rear drum?
Oh Keith - rear is a single disc,m front is a dual disc. The one I worked on was the rear.
Today I spent about 7 hours trail riding. :)
It's good that you could get by with rebuilding the old units rather than buying new ones. I bet they are unavailable.
