Default 2008 Scion tC Clutch issues?

I have a manual 2008 Scion tC that is having some problems with the clutch. About a month ago, the clutch was replaced because the clutch pedal was sticking to the floor. 2 weeks later, the NEW clutch was having the same problem, the pedal was sticking to the floor. After looking into, I found that the most common cause of this is a bad clutch master cylinder or slave cylinder. I replaced the slave cylinder and almost immediately the clutch started to work after I bled it. After 5 or 6 times of pumping the clutch pedal, however, it stuck to the floor again. Does this mean there is air in the system, or does it tell me that it is actually the master cylinder that is having problems? If it is caused by the air, what is the easiest way to remove all of the air bubbles?


Also, if I were to replace my clutch & flywheel to a better street performance one, which one should I go with? I have been hearing good things about ACT performance clutches. Do you have a link to one specifically. It might also help to know that I do have a turbo installed.

Any time you replace one of the hydralix master cylinder or clutch its always best to do both. In most cases they are the same age and will both quit working at almost the same time. Put a new master cylinder on the car and bleed the system this should take care of any problems if you just had the clutch done. If you just put a clutch in it Use it. There is no point in taking out one and putting in another new one. When the car was engineered They put a clutch in strong enough to hold the turbo si it should be fine for awhile now. You can get 100 thousand miles or more easy if you learn how to treat the clutch right.

The car should have enough power that you do not need to slip the clutch to get extra power. You should use the rpm range of the motor to take you through the gears. The only time you have to abuse the clutch is if you launch from a standing start. But if you get the car rolling in first gear in the right rpm you can minimize the heat build up which melts the clutch over time.
