Fluid for the most part. High temp stuff.

Spring or chunkier clutch also. I think there is a technote which adds a spring.

The spring added to the clutch pedal looks inelegant!

More myth and legend I fear, I thought we were living in more enlightened times.

How on earth can you boil the clutch fluid when it is so far removed from the friction surfaces, and so well heat sinked to the gearbox?

There is along thermal path with plastic parts and bearings?

These symtoms suggest to me something goes wrong with the pressure plate which moves the release fingers to the released position and the pedal goes limp. Pumping it then cause it to go hard with a hydraulic lock. Slow down/cool down it returns to normal and the pedal resets its self.

The article doesnt actually say the fluid boils, more it just gets contaminated.

They say to use decent fluid to help prevent boiling...but that's different from saying it will or can boil.
