anyone care to give me some insight. Lately whenever my car heats up the clutch pedal gets softer. it seems to go through phases. sometimes it'll get softer. other times it'll be fine and stay firm. the slave and master were recently replaced. the system has been bled countless times. this issue started happening a few months ago and still comes and goes. anyone have any idea what could cause this?

It sounds like boiling clutch fluid. Swap it out for some better stuff (RBF600, etc.) and consider putting heat shield/wrap over your slave cylinder and downpipe.

It happens on Subarus and other cars in hot weather too, and it is related to old/dirty boiling clutch fluid, normally.

thanks man i guess you're right. cause the fluid is black. also when i'm "runing down the quarter" by the time i'm ready to shift into 4th the pedal practically is dead sometimes. So i guess i'll replace it with better fluid. i'll try the rbf stuff.
