so whats your disengagement point.? Since truck slaves will only push little over 1 inch.and fork will not go any further after i fixed the clearance problem.should we blame it on luk which is supposed to be oem?i have been reading about luk clutches requiere a longer pivot ball but i think that does not have anything to do with a hydraulic set up

Edit: But thinking back I don't think I've ever seen a hydraulic clutch setup with a return spring. You have any examples of this setup?

But I don't know what setup you ended up with. Are you still using a regular GM fork or a C3 fork? What was your clearance fix?
And there are at least two truck slaves with different travel. I'm using the Chevy S10 slave cylinder. The early (~1984) version has a 0.94" bore and less travel than the later (~1989) one with a 0.807" bore. I tried both, think I ended up with the later version.

I tried a Camaro stile throw out fork in my c3 , waste of time that was.
Then went back to a vette fork and that still hits the firewall when disengaged, with the standard chev pivot .
I fitted an aftermarket adjustable pivot and made enough room , so that every thing works with out hitting,
I'm running a tremec 6 speed magnum. next time it come, I`ll look at a late model hydraulic throw out bearing set up.

I'd say mine disengages about 1/3 from the floor.

today i made an adjustable push rod for the slave and bleed it again its %100 bled .and push rod moved 1.1/8 " exactly every time and wheels turn by one hand in gear it disengages about few cm before the master bottoms out.i am on break now as i got dehydrated after 6 hours of work under the car.clutch kit is luk brand .i just learnt mcleod's kit disengages much sooner.i dont know why it takes so much travel to disengage maybe i just gave the answer
