Hi everyone
I really hate posting this again but I know the guys with a stick have had your foot on the clutch pedal at sometime. I'm sure your vette wasn't your first stick. Now with that being said, I have a new 2016 Z07 and there is NO clutch free play.

I've talk to some people I know and they say that's normal. Hey I'm over 60 and never had a clutch pedal with no free play.

I have been a lurker for a couple of years and me buying this vette is a whole different story. How's this one I'm writing this from a nursing home. No BS


Again I sorry for posting this again but I would like to get an answer before I put any miles on it. I hope everyone understands.


Thanks much

Can you explain what you mean by 'free play'?

I'd definitely say the C7Z clutch needs to be on the floor when you shift. There's no cheating a shift with a partial clutch depression unless you want a little grind.

The nature of hydraulic operated clutches is there is no free play similar to a mechanical linkage where you have some pedal movement before you feel any resistance. If you want some there is probably an up stop on the clutch pedal linkage which would allow some free play before the clutch master cylinder piston rod is moved. I'm guessing about this as I haven't looked under the dash.

Mechanical linkages required some free play to ensure the clutch disk was fully released. With a hydraulic system the pressure plate springs just push the fluid back into the master cylinder from the slave cylinder.

I think the OP may be asking about engagement point. Some cars engage when the pedal is released just a bit but others engage when the pedal is almost fully up. There does not seem to be a lot of consistency.

what I'm talking about is when the clutch pedal is at the top (no foot on the pedal) and as you begin to depress the pedal you can feel the throw out bearing engage the fingers on the clutch.


What I was concerned about is without free play the throw out bearing is two things 1 if the throw out bearing is always in contact with the fingers you fry the bearing or 2 how do you know the pressure plate is fully engaged.


I hope I didn't cloud the issue. I would have made a crappy teacher and I used to run blown nitro race engines. But that was 30 year career that's another story.

Tolerances in stack height of clutch assembly, engine block, flywheel, crank shaft and bearing can all add up to possibly amounting to enough if all off in the direction of increasing the gap or narrowing it for a noticeable difference. Though I'd try bleeding the clutch first to see if it helps the play in the peda feel as air or contaminated fluid will alter the engagement of the slave cylinder actuated by the clutch master cylinder. Initial break in, no lift shifts and clutch dumps will accelerate the fluid getting contaminated with clutch disc material as the "sealed" slave cylinder isn't immune and fluid needs to be periodically changed if driven aggressively. If not bled from bleeder then by the "Ranger" way atleast.

Hope that helps, Chris

Freeplay exists in both mechanical and hydraulic linkage clutch systems. It is the distance, usually measured in fractions of an inch, that the clutch pedal can be depressed before it starts to 'work,' or disengage the clutch. You can barely feel it -- it's the point at which you first feel clutch resistance. Original intent was to prevent clutch slippage. My MY Z06 has freeplay -- and I can feel it. But far less noticeable than in any other manual transmission car I've ever owned.

I think that most of this is due to the engagement being at the top rather then the floor

Hotdogone, get the heck out of the nursing home and drive the darn thing. Everything is fine. It is because of the hydraulic clutch.

I own two 1930 Chevys, one 1931 Chevy and a 1963 Corvette all with stock clutches so I know what you are talking about.

So get out and drive it. It is FINE.

Right. I should have added that.
