Clutch pedal fade?
 

I am not having any problems with my clutch pedal when just driving normal but if I decide to start banging gears in at high/redline rpms it seems like the pedal gets "softer." It shifts fine and I have no noises or vibrations or anything else going on, but I have never experienced something like this before. It doesn't feel like its losing pressure or slow to return but just easier to depress.

Has anyone else ever have this occur?

Thanks, Jake
