Yes, that's what I'm thinking. No idea how many miles were on the used SC, but the paint was starting to wear off, so I'm guessing several years' worth at least.This is just a wild guess, but if your slave cylinder is already a used replacement with unknown history, then it could (in theory, of course) be that the SC piston is worn just enough to rock back and forth and start to get cocked sideways in its housing and bind up that way. Not very likely, I know, but it sounds like everyone is starting to grasp at straws here, and I figured I'd put the possibililty out there... shrugs his shoulders
Only real fix would be a new SC. Sucks cost-wise, but I don't want to have to do this again in another 30k miles.
