clutch pedal sticking

Hey everyone
Got my turbo fixed up (from my laSt thread) now I have another issue.
For a while now my clutch has been sketchy. It hasn't been slipping but it seems to stick when I hard start or accelerate hard. Let's say, passing a car on the highway or taking off at the green - if I break approx 2200 rpm it will happen almost every time. The pedal is exteemly stiff and sometimes doesn't actually engage the clutch (as in the truck is still in gear and hard to get out ) until I put my toe behind it and pull it out again - pump 1 or 2 times then fine again.
My reservoir is about 5/8 of an inch from the top (I can't see the min/max lines) so I am wondering if maybe just a gravity bleed will do the trick? Or maybe replace master / slave cylinders? Any reason why I could believe it to be the throwout bearing? Any ideas are helpful

Thanks!

Its the stock pressure plate. Go with a South Bend clutch kit and it will go away.

I guess there is a self adjusting system on the stock pressure plate that cant handle the power. Yes I have had some experience with this, exact same symptoms you stated.

Hrm well I have changed out my master / slave assembly all to no effect - figured it was the easiest to start with and prob should be changed anyway if I change my clutch / pp assembly. I have a Luk clutch kit ordered - any expierence good or bad with these? I ordered the 500 hp assembly

Well the stock pressure plate and friction disk are both LUK, says it right on them.

Yes I think it would be better than your old stock one, just not the one I would buy.

Well I jusat picked up the kit I am not sure why I was told it was LUK cuz it has south bend right on the box - I guess that is a good thing.
1500 for the kit - good deal or crap?

Sounds a little high but if it works thats all that matters. Where did you buy from?
