New clutch problems
New clutch problems I've recently installed a LS7 clutch in my Camaro and since then I've had clutch disengagement issues. I've bleed close to a gallon of brake fluid through the system so I'm fairly sure there is no air in it. The pedal also feels good. Problem is the clutch won't disengage enough to get it in gear. It's close, if I start the car in gear it barely creeps with the pedal down.
My question is, I bought the slave cylinder used with about 10k on it from a board member. When I got it, it had a thin spacer (about .040) behind it which I did not install. Was I supposed to put this in?? I'm about at my wits end here and actually consittering buying a stock clutch to see if it fixes the problem.

How many miles have you driven? First, that spacer would help because it's going to move the throw-out bearing that much closer to the pressure plate springs. If you haven't driven it yet, get it in and run it for a while. As it breaks in, the pedal engagement point will move up off the floor. This should happen fairly quick though (less than 50 miles). If you've already driven it and still have the problem, put the spacer in and try it again. If that's the case, I'd go with a thicker spacer like the ones Spec includes with there kits.

With an LS7 unit you should not need a shim, as mentioned above. That being said, as I mentioned in another thread, I am currently looking at part variance for the stock hydraulic assembly (Slave and Master). What Slave/Master are you using (LS1 or LS7)? What are the part numbers? Let me know. Thanks!!

Verdad Gallardo So I've put about 75 miles on the car and the clutch pedal is comming up. Problem is the clutch still will not disangage and it won't go in gear without killing the engine. I'm starting to think maybe the clutch disc is hung up on the input shaft and draging against the flywheel or pressure plate.
Anybody got any other ideas before I pull the trans to inspect it???

Ok this is wat i found out, its a possibility that your flywheel has been surfaced too thin, or if the pilot bearing is messed up your clutch will not disengage, or if disc is hung up on input shaft so drop that trans again and access ur prob

OP, before you end up breaking anything, pull your tranny out and measure for a shim. There is a great shim measurement write up somewhere here on this board.
The LS1 and LS7 clutches are not completely identical. The TOB on the LS7 slave sits a fraction of an inch closer to the PP fingers than on an LS1 slave.
And not every slave is exactly the same. You should measure for a shim with every clutch install just to be sure. That 3/4" travel you have before the pedal gets solid is the distance the TOB is traveling before it touches the PP fingers. A shim will put the TOB closer to the fingers and shorten that distance. The shorter the gap, the longer the throw you'll have on the clutch.
