    If the seal is popping out of the cylinder you have probs. with something in how the shoes are set up. From the factory you can wear away all of the friction material and half of the metal before the seal would even think of comming out. My guess would be: wrong shoes, wrong link pins (that go from the wheel cylinder to the shoe) or star wheel, or being searously out of adjustment.

    I'm with the earlier post. Just go with 'new' cyl's! With the warranty on 'em.... less time messing with rebuild they're worth it!

    Do it once, and do it right!
