Hey guys, you have a very informative site and I hope you can give me some insight into my problem.
I have a 95 CK 1500 with a 350/5 speed and 75000 miles on it. I have had problems with the clutch for quite a while and it is getting to the point where the truck is difficult to drive. You have to push the clutch pedal all the way to the floor to get it to disengage and if you let it up (even 1/16" it seems) the clutch begins to grab.
It has a sealed hydraulic clutch (no bleeder valve) and there is about 1 or 1 1/2" (measured at the end of the pedal) of free travel in the pedal before the push rod contacts the master cylinder piston. I have replaced the clutch disc, pressure plate, throwout bearing and pilot bearing but to no avail. I checked the balance of the clutch components and they all appeared to be in spec.
The problem seems to get worse as the truck warms up and after driving for 30 minites or so the clutch will sometimes grab even with the pedal all the way to the floor.
The clutch pedal is also very hard to push but I just write it off as being a truck. Not sure if this has any bearing on the issue.
Thanks for your time and I lood forward to hearing from you.
