I had a new clutch installed about 6 mo ago.. a stage 2 non-modular that I got off ebay. About a week ago I was driving the car and it got to be pretty hard to disengage the clutch. I had to jam the pedal all the way to the floor after 2 days for the clutch to disengage. It sort of seemed like it got a bit harder to shift after the car ran for a bit too, and that the clutch pedal was vibrating a bit more then it usualy would (could be wrong). The faster I pushed the pedal the better it disengaged.

I checked slave and master for leaks and found none, the fluid was pretty mucky looking and nasty so I bled it with another person with some dot 4 synthetic... till it came out totaly clear looking and nice.

The slave also moves when someone presses the pedal. I am not sure if it is moving enougth, or fast enougth (nor do I know how I would tell). The clutch isn't slipping at all and once its engaged its fine.

So I guess my question would be is it my slave/mater or is it the clutch or pressure plate and what could I do to further diagnose this problem.

Thanks!
