took my mc about a week to go bad after my brake line went (and i successfully replaced the line and bled the brakes).

i think the seals can pick up some dirt, but not tear immmediately. then, after moving back and forth with the dirt on them for awhile, they tear.

anyway, good luck. <img src="/forums/images/graemlins/cheers.gif" alt="" />
