...while driving!, was on my way home from work and had just left a light, went to go for 2nd and the clutch wouldnt push in, stuck in first and had most of town to drive through, plus anouther 2 miles after i got through town to get home. so i pull into a parking lot and turn the key off, get a ride home to grab a floor jack and a creeper, sure enough what i thought happened did. somehow, some way the quick-dissconnect had came apart, this was all brand new over a year ago, have put over 10,000 miles on it since then, i tried putting it back together, went to push the clutch and it popped right back apart. this is a "new style" slave that has a clip you can remove that retains the line from the master. (autozone slave) i thought the edge of the clip might be "rampped" instead of a square edge, so i pulled it off, flipped it and put it all back together. so far its holding, hope it doesnt do that again, theres no way i know of to secure it togther besides the clip that it came with, ive looked but havent seen any other mention of one of these coming apart. glad i wasnt far from home, or pulling the trailer! at least the system didnt need bled, lost very little fluid when it came apart.
