On my 93 yj wrangler the clutch pedal became non responsive. The fluid was a little low so i added some & bled the slave cylinder. When i pumped the clutch after bleeding, the fitting came apart where the line from master cylinder ties to slave cylinder. I have reconnected the line & added fluid. While pumping clutch i get same results repeatedly. I replaced the slave cylinder a couple of years ago because fluid leaked out of it. Is my problen with the slave cylinder again? Can they get clogged up?
