Hey everyone, i finally got the old clutch in my Legacy replaced for a ACT Street kit, and I think i may have found the reason why the old one went bad in the first place. I have noticed that whenever the car is cold, the ACT clutch is really easy to push in, but gets harder as the car gets hot. Also, i was looking under the dashboard and i noticed something maybe leaking from the master cylinder's rubber boot. I know that if brake fluid is coming out of the boot then the master cyl. is definately gone, but would that explain the change in the clutch pedal feel? Also, does anyone know where i could find a rebuild kit for it if that is the problem?

Thanks everyone
