You're wondering: is it good news, or bad? Well, it's a bit of both. First the bad news. The front brake shoes, which looked pretty good from the side, didn't look so good when I took everything apart. Plenty of pad left, but what was there was cracked, pitted, and brittle. My prediction is that the back shoes will be in similar condition. I won't tackle that until the front ones are finished (for starters, I don't have enough jack stands).
The good news is that the brake hardware cleaned up very nicely using the multimedia blaster and ultrasonic cleaners at work:
Outlook is that I will get my wheel cylinders and new hardware on Monday. I will probably use all new hardware, and keep the above set as extras. (Why not? I'm planning on this set of brakes lasting a long, long time!)
