Another CSC failure?

The pedal sticks down if there isn't sufficient hydraulic pressure to return it. Definitely sounds like air in the system. Now the reason the air is there is because of 1 of 2 things, either the fluid boiled due to fluid contamination that lowered the boiling point, or air entered the system somewhere. The later seems unlikely at this point as if that were the case then fluid could also leak out the same place.

Just bleed it, takes all of 5-10 minutes. Takes more time getting the car jacked up to get access to the bleed screw.

Bleeding isn't a bad idea. If anything, worst case scenario would be guaranteed, so I might as well take half an hour and bleed with fresh, 10 dollar fluid than dismiss it immediately as CSC failure.

I do not know if this post should be here or not but here goes.

I just changed my brake fluid to DOT 5.1 and had some left over and changed my clutch fluid. It was black and looked like it had well over 13,000 miles on it.
