Hydraulic clutch system on a 1993 Saturn SL2

Hydraulic clutch system on a 1993 Saturn SL2

(OP)
We have replaced the clutch master cylinder, and the slave cylinder, but we are still unable to get good resistence in the cluth when applig pressure, we have gravity bled the system numerous time. We can shift to all gears as long as the engine is not running, but as soon as we start the car, and try to engage/disengage the clutch it will not go into any gear. There is no grinding in the transmission area. What else can we do besides TNT?

RE: Hydraulic clutch system on a 1993 Saturn SL2

(OP)
    We see similar problems in fluid control systems. These often have a sight glass at the high point, so one develops a feeling for amount of air and how fast a fluid stream makes it disappear. I'd say that your problem is in the gravity bleeding. It isn't unusual for the stream of bleed fluid not to have enough velocity to move the air out of the system. Check that your connection between the master and slave cylinder does not have a high spot. The entire connecting line MUST be lower than the bleed point. If you have gotten a bubble in a high spot in the connecting line then gravity bleeding will not remove it. Pressure bleeding may work. Another thing that works to reassemble the system while making sure that component is filled with fluid and purged of bubbles.
