So i have noticed the clutch starting to feel different, and just thought it was slowly on its way out. well the other day tried to drive car and clutch did nothing until the very bottom, checked fluid and it was gone. so filled and re bleed and it feels fine......for now. where did it go? this is not normal. had car for over 100,000 miles and never had this. if i keep it full and bleed will it continue to work? any thought and or opionions are welcome.

 

Might have a slow leak. Why have you never flushed the fluid in the 100k miles? Mine needed flushed nearly weekly!

 

why dirty fluid does not compress just the samew as clean fluid?

 

boils quicker...... but if you haven't had a problem I guess its fine. a lot of trash builds up in the slave cylinder also. if you flush it and let the fluid sit in a clear container you can see the junk settle to the bottom.

 

Dirty fluid has little bubbles in it that do compress which is the exact opposite of what you want. Those little bubbles compressing causes the slave to not move out as far, which means your clutch isn't fully disengaging. Just bleed some fresh fluid through the system and see how it feels afterward.
