I have a 2004 Aveo but my issue was the Master Clutch Cylinder was sticking to the floor. The Clutch would disengage but the pedal was stuck on the floor until I lifted it back up manually. This happened at 123,000 miles. I replaced the Master Clutch Cylinder with a cheap ebay one and the part was faulty. It sucked in air from the loose fitting that was on the Master cylinder body. That resulted from a clutch pedal that would stick to the floor and not release the clutch plate. So I got one from O'Reilly auto parts store.
I heard the throw out bearing is really cheaply made for the Aveos and do fail which is what your fork on the clutch uses to disengage it.
