Guys, I had the same thing happened to me on Friday (pedal to the floor - no leaking, fluid level was fine). Dealer flushed the DOT3 fluid (OEM) out, filled with fresh DOT 4, bled properly and problem solved. Our cars run very hot and with the fluids absorbing water over time, thus lowering the boiling point, the DOT 3 fluid boils at much lower temps rendering it useless.

Yep. Bleeding the clutch after track days is always a gruesome sight :)

I have a question then.. If I am running through a canyon, staying in 3rd gear almost the whole drive through.. Speeds anywhere from 45-80, not shifting much at all, not using the clutch much at all, am I still effecting slave/master cylinder? or fluids?

this is way to vague. what might not be much to one person could be alot to another.

if you are using the clutch and shifting then yes you are using those components and fluid.

i think im a little lost on what your asking though

Heat transfer is still occurring.

They are talking about the fluids getting hot.. well, i asked if I am not actually using the clutch as much as I would on a real track, is it still getting hot...
I honestly dont know what i am talking about.. I am not too educated on cars. I know the basics.

But I dont like driving and all the sudden the sang Slave goes out. I have never had that happen..

The CSC failure is most likely due to heat. Hard driving, regardless if you are shifting, is generating significant heat.

To answer your earlier question though... Hard/high rpm shifting will certainly be harder on the clutch, fluids, and csc, than staying in third, but not eliminate wear, or the need to change fluids appropriately.
Once you do it once, you'll see bleeding the clutch is a REALLY simple job that goes a long way.

Cool, I will remember that.. Thank you!
