I put in a Spec Star Stage III clutch, 1500 miles.

My pedal travel is RIGHT at the top!
I'm talking you push the pedal about 1/10th in, and it is completely disengaged (reciprocal for engage, makes it interesting to take of smoothly without lunging the car).

Is there a way to adjust the LT1 hydraulic clutch setup?
My car is a '93 Z28 (6spd).

BTW, 1500 miles and my Spec Stage III Carbon is STILL breaking in, still improving, but still chattery.
I probably should've gotten a Stage II.

Thanks for any help!

As far as I know there is no way to adjust a hydraulic clutch.

 

Spec says that the most likely cause is my flywheel was surfaced too much.

The limits are .008"-.010" PER SURFACING, and you can surface up to 3 times, so the max material you can remove is about .030".

I think the shop that surfaced my flywheel took that much or more.

My clutch doesn't slip, and I have a TINY amount of travel at the top of the pedal, so no harm no foul.

But if I ever feel it slip, I'm gonna just take it easy and plan a weekend to pull the flywheel and replace (sigh).

Who knows, may go a long long time w/out problems, so I'm just gonna drive it until something gives.

Thanks for the feedback!

there was another post about this awhile back, try searching for it. I think someone said to put washers inbetween the firewall.

 

Teeman, I don't think that is your problem. It would be reverse if you had too much material taken off the flywheel. I bought a junkyard flywheel and had it resurfaced. It worked fine until I burnt that clutch up and resurfaced it again. It would NOT fully disengage when the clutch was depressed fully. I thought it may have been my hydraulics, so I even bought a new set. No dice. I was about to buy a new flywheel because no one had a solution here. My friend went to the local machine shop and found a flywheel shim for a Chevy. Took the trans/clutch out and put the shim in. Clutch works PERFECT now. Actually, I got a hair too big of a shim, since if I push the clutch too far, I can hear the throwout bearing make noise. No biggie thouh. I think the problem with yours is that the fingers on the PP may be too thick. Just a thought.

 

I can vouch for the shim, a lot of 383 guys need one as well do to the crank.

 

why not just get an adjustable slave cylinder. it does allow to change pedal feel a little bit

 

An adjustable slave cylander would be good to adjust the pressure, after the fix. But that doesnt fix the flywheel issue. Get a new fly wheel or a shim, then get the adjustable slave.
