driving home tonight i lost my clutch pedal unless pumped and pressed quickly,got it home and checked where leak was and found it was peeing out of where the pipe goes into the slave cylinder, so i removed the slave cylinder and found a little o ring had split, managed to find one in my plumbing box that was slightly bigger but it fitted with a squeeze built back up bled and all ok again but just wondered has anyone else had any problems with these seals etc in past?
