89' 80q clutch question

[David M Sugerman <dsugerma@runet.edu>]

	Last week my clutch pedal started sticking about an inch or two 
in without popping back out on its own. The car changes gears and pulls 
perfectly, and all fluid levels are where they should be (no leaks). 
Could this be old grease on the pin that goes to the clutch slave 
cylinder? I dropped the panel under the dash to take a look, and even 
sprayed some silicone on the part I could see. After driving for a few 
miles the problem went away only to return several minutes later. If the 
pin is the problem, does anyone know of the best way to go about 
removing, cleaning and re-lubing it? If that's not the problem, what else 
could it be? I forgot to mention the car has 122k miles it, and the 
clutch has never been tampered w/.  

Thanks!
