Well, I have a new clutch, but my master cylinder was changed out a couple years ago. It looks like it's going again. If I hold my foot on the pedal in neutral sometimes, it will slowly drop to the floor. It becomes a pain because my clutch's grab point drops to the floor, causing the car to engage faster than I think it will. Is this really the master cylinder or will a simple clutch bleeding do the trick? It seems to have gotten worse over the past week or two. Fluid in the resovoir is full.

 

try and bleed it and see if that helps before going and buying another when just bleeding it may help
