Clutch pedal problem

[johnm]

Is anyone experiencing a clutch pedal that fails to return to the normal postion after attempting to change gears. I just sold my 04 automatic coupe and am looking at an 07 Z. the guys over in the C6 ZO6 forum are all complaining about the clutch. I was wondering if this is only a C6 problem or is it a corvette problem (or is it just that C6 guys are just a bunch of whinny crybabies)

Some guys find relief by cleaning the fluid out of the master with a large syringe and replacing. Recover the clutch master and

Then pump the pedal 20 times (all with the car not running at anytime) ..

Then open the master and remove fluid and then replace.

Be careful as the fluid is caustic to the cars paint but the whole procedure takes about 5 minutes.

I found some relief with that "ranger" procedure but recently (after about 20K miles) replaced the clutch, the master, the slave, throwout bearings, drive shaft bushings , the pilot bearing and used thermotech heat wrap on the clutch lines.

So far its like a new car.

Good luck.

The only times it has happened to me is at the drag strip. It has happened twice. C4C5specialist explained to me why that happens, but I don't remember the details. In any event, I have had it happen only twice in almost 50,000 miles, and it only happened under the most severe conditions.

clutch spring assist ?????????????

Check your Clutch Assist Spring. GM has a better style then the one currently in 2005-2008 (including the Z06's)Corvettes. I've seen the new competition(better shift) style on ebay.

It all comes down to clutch fluid. Keep it clean!!!! One vendor sells a hose to connect to the bleed connector that routes it up next to the resevoir. That is the easiest and best way. After replacing my clutch master and slave for over $1100 and having it get spongy again after only 15,000 miles, i looked all over and found it is just like boiling your brake fluid if used hard. the turkey bastor method also works but is slower. i now change mine twice as often as my brake fluid. no problems since. give it a try.

HI there,
And just how many reasons are given as FACT as far as the ZO6 clutch goes???
Anyway, here are a few tips about clutches in c5 and C6.
First, NEVER NEVER NEVER remove the over center bias spring from the clutch pedal assembly. This creates problems with clutch hydraulic fluid stress and leaves pressure on the slave cylinder, which could overheat it.
Second, clutch hydraulic fluid should be changed every 2 years/24000 miles using P/N 88958860.
Third, aftermarket clutches create more problems due to changes in installed height of the clutch pressure plate fingers and INCORRECT INSTALLATION.
Fourth, these are NOT DRAG RACING CLUTCHES. They are engineered to give long life over road course, normal street driven stresses.
Put these facts together, and your c6 clutch will last a VERY long time and give the feel and engagement without sticking.
Allthebest, c4c5

Thanks for the info c4c5, none of the clutch problems I referred to were based in fact, Just a bounch of guys on this site b******* about it. Seems like a lot of people but when you boil it down it is a very small percentage when compared to how many are out there doing fine. this is the first manual tranny I have ever owned so your maintance tips will come in handy. I never even thought of changing the fluid. Is this difficult to do? Something a guy with moderate skills can accomplish? I don't mind spending the money to have it done professionally, Its just that it kills me to take my Z06 to the dealer for work and watch as some pimple faced 17 year old hops in my car with dirty clothes, greasy hands and occaisionally a screwdriver in his back pocket only to hit the wooden planks used to ease the angle of the lift at 20 mph.thanks again johnm
