My clutch pedal recently started be low (about 2/3 from the top) in the morning, then slowly work its way to a full pedal over the course of driving after a half hour or so (1999 Saab 9-3, base model). The replacement slave (the first one blew out) and master are very new. The slave was pre-bled before the tranny was put back in, and I pressure bled the replacement master (the first one was defective). I am not losing any fluid, at all. These were purchased through eeuroparts.com, so they are quality brand name parts. Any ideas anybody?
