A bit of history to start: Last summer my clutch main went out and I had it replaced, but I did not replace the clutch slave. After some research I found that the clutch slave often soon follows, so I bought a replacement and changed it in September. Everything has worked great. I moved up to Wyoming for the winter, and every thing drove as expected. Just last week I drove down from the mountains back to sea level, and I had a wierd issue with my clutch. Once I got to Oklahoma (driving Wyoming -> Louisiana) the clutch started to slip, it was as if the pedal was being pushed ever so slightly. To correct the problem, I just loosened the backstop on the clutch pedal, to allow it to swing back further. This solved the problem, but all of the sudden my pressure dropped dramatically. Now instead of having 0 dead pedal, with the clutch picking up with about 1-2" of pressing the pedal, I have to push almost to the floor to get the clutch to pick up, and it doesn't seem as smooth. Ideas? Is something failing? I'm thinking I should drain and re-fill the fluid, and check my adjustments to make sure it fits the manual.
