I decided to flush the brake fluid on my '95 SE. When we started in on the clutch, some fluid came out of it, but then the pedal went straight to the floor with no pressure at all. Since then (overnight) the feel has come back to almost what it used to be, but still not quite right. Does anyone have any ideas what happened or if I need to do something to make it work correctly again? There is no air in the system and the reservoir is full. But I don't know if I should be driving it, although it seems to work ok.

1995 SE Mods- SVT Exhaust. SVT Intake, E1 SVT Wheels, BAT Euro Suspension, 20% tint sides and rear, 50% tint windshield. Future Mods- A new third syncro. It's my boring daily driver that I autocross on the weekends.
