hello, i just did a clutch pedal adjustment and i notice a black grease like substance coming out of the clutch master cylinder. it isn't drippy but feels almost like grease. is my CMC failing or is it grease?

 

I think your CMC is leaking....... Pics??

 

Its ok for there to be black grease where the rod meets the cmc but if you see a drop begin to form below the cmc then it is leaking. You can touch it lightly with a paper towel and see if it soaks in some liquid if it does then yes there is fluid leaking
