[s-cars] Frozen Guide Pin on Rear Caliper

[David Kase]

It's just built up muck.  Come to think of it, I think I put vice grips on the area of the pin near the end.  Then I would hit the vice grips with a hammer.  Then turn it back and forth and do it again.  In between hit it with a little heat and penetrating oil.  Don't try to hurry it, let the oil get in there and just keep working it.  The last one I did I thought would never come out but it eventually did (and there was much rejoicing)...

What holds the guide pins in?  I can turn the "frozen" pin, but not
move it in or out.
