My 99 s-10 work truck has the hydaulic slave cylinder that sets directly behind the throw out bearing. You had to burry the pedal in the flor mat to get it to release, so I had the clutch, presure plate, master and slave cylinder replaced, all with no change whatsoever. What the ---- else is there other than the line between the master and slave? It's not leaking, how could it be that? Anybody got any ideas?
