2001 cavalier.clutch seems to be at the top of pedal travel or not far from it. Can this clutch be adjusted?

The adjuster needs to be reset. It should then automatically readjust to provide the proper amount of clutch pedal travel.

Your clutch disc is worn out.

Possible on older cars with normal clutches/not as easy with the newer cars that have hydraulic clutches.

A clutch pedal takes MUCH more travel to function correctly, when compared to a brake system...

A clutch needs to be replaced (maybe) when it SLIPS, Chatters, Or fails to release...

Other than that, the clutch will need to be adjusted to allow for total release of the relese bearing when pedal is released, and full disengaugement when pedal is depressed....Have a mechanic look at the adjustement, as proper adjustment gives longer clutch life. This is a periodic adjustment item.

Sounds like the clutch assy is about worn out. Most hydraulic clutches are self adjusting so when the clutch disc lining wears thin it takes more pedal travel to engage.

The clutch is not fully releasing. You can try putting it into some other gear first, then rapidly moving to first gear, but really, you need to either adjust the clutch, or get it repaired.

I assume it is a cable operated clutch. If so the adjustment is tightened so that there is about 1/2 to 1" of pedal travel to clutch operation, provided the gears can be selected smoothly.

dont know

This is a hydraulic clutch you can't adjust is.

first i would try adjusting the clutch cable because commonly people with think that they're clutch is going out when really just the cable has gotten stretched....try adjusting that first and if that works then you should be fine for another couple thousand miles but if you want to not have to worry bout it for awhile i would just replace teh clutch assembly....usually ranges from $200 to $450 depending on the clutch set and the mechanic that does the work for you. Let me know what happens. :)
