I had the calipers turn up in the mail this week, as they were not on the bike when I received it. I pulled them down today and they seem quite reasonable for something that's been sitting for so long.
The pistons are in good condition up to where they seal, but obviously they will need replacing. The Ali part of the caliper has a few dark splotches in it, but there is no real corrosion and it feels smooth to the touch and the piston still slides in and out easy yet is snug.
Question: At what stage do you guys consider there to be too much discoloration/corrosion to go the the level of re-sleeving the caliper? I'm happy to get it done, but I don't just want to do it for the sake of doing it.
.....and a couple of pics of the seat hinges
On a different note, when I restore something I usually try to accumulate most everything(that I can see visually) that I know needs replacing prior to pulling things apart. It was suggested to me that the Bottle engine may be my biggest hurdle and the I should start with it.......what say you?
