Clutch Pedal Going limp

Knowles' Z06 · 02-23-2009, 11:58 PM

Can anyone explain why this weekend while at the SGMP drag strip my pedal would go limp...?

For the first time I used Mickey ETs drag Radials and they really seemed to hook nice 1st to 2nd and then 2nd to 3rd the pedal was on the floor board with in a second or so, it sprag back up...I have spoke n to some that say it was slipping from the heat and others that say it is a RPM and speed ratio issue...I wonder about the heat concept because itis not like I was drag racing all day there was at least 20-30 min usually longer before I was up again...Also it only happened here and there it seemed liike when I had a really good launch and the car was really sticking with a lot of pull....limp city

even though I have to figure this out I had a blast and put up a 11.395 at 127.8 mph not bad for a 1/4 mile with a limp pedal LOL

When is the last time you changed your clutch hydraulic fluid?

If it happend at high RPM the centrifical force over powered the clutch springs. It might be time for a new clutch.

since my car has less than 5k miles I doubt I need to change the fluid yet...I really think it is a computer issue or something like that..

You might want to check the fluid anyway. If it looks like ink, then it may be a real good idea to change it.

I'll clue you,the computer is not in any way in control of the clutch! With that said,the fluid thing has more to do with the age than miles!!As RichZ said,you probly need to check it,there was a problem with the fluid gelling and turning to a Ink like sludge!!

Also has to do with heat from track time.

Common with the stock clutch. This has been a constant battle since the first Z06 in 2001. There is a self adjusting mechanism in the stock pressure plate. Centrifugally, it is fooled into a false self adjustment at high rpm speedy shifts. The first 2001 that did this got at least 5 clutches and hydraulic systems under warranty. This never solved the problem. As soon as the warranty was up, an aftermarket clutch was fitted and the problem never surfaced its ugly head! Fast forward to 2006, thought that that problem would have been rectified by GM. Nope, still has the self adjust built in. Not as prevalent as before, but still there. Bad news......ZR1 too! The real fact is this, GM has a warranty to honor. They do not want to buy transmissions and rearends so they put in a less than stellar clutch to be kind of a fuse in the system. Guess what is not covered in warranty? Wear items like brake pads and Clutches.
