and you have to remember its 500miles of CITY driving. Or like back road mountain driving, you want downshifts, and lots of up shifts. Sitting there at 3,000RPM on the highway isnt breaking it in...

but yeah, you always have to re adjust the pedal due to getting new clutch parts.

I guess ill have to wait more to break in the clutch then, its going to be tough though cause I live in a small city.

Hey guys, well I had no luck with the free play adjustment. I adjusted the free play and the clutch pedal heigh and the clutch still engages when my foot is almost all the way out. What I did notice is that my Clutch Master cylinder is leaking fluid from to the outside and to the inside of the car. So I was wondering if this could be my problem???

My clutch slave cylinder is brand new.

But wouldnt a bad clutch master cylinder only cause bad clutch engagement? Cause it starts to slip at around 4,500 rpms after the clutch is engaged. So im confused here.

You pretty much answered your own problem.

Bad leaking clutch master cylinder


That seems unlikely. Usually a leaking MC will make the clutch not fully disengage instead of slip.

MC=Master Cylinder.

Pushes the piston out from the slave which pushes the fork to release the pressure plate.

O yeah K know that LOL.

So anyone have any ideas??? So it cant be the master cyliner right?

Could be a lot of things, if you checked the preload on the pedal and that wasn't it... then pull off the inspection plate and see if there is any oil residue evidence of a rear main seal leak.

If you've confirmed the preload is good, and there is no evidence of oil... then it's time to drop the transmission for inspection.

Lets say the clutch is not fully broken it to. So do you guys think that if theres damage to the clutch right now (glazed or something), that with another 500 miles or so it would be alright again? Cause the 600 miles I have into it have been mostly highway miles.

First off, thanks goes to aaron for the tech help!

with a stock ct their is no way you will overpower the clutch you purchased from me. stock 60k mile clutches hold up at this level (300-330 hp) and the clutch I sold you is stock aisain pressure plate and a act 6 puck disk. Even with Aarons 15 pecent greater then stock estimate you would be needing to put down 350-400 hp to make it slip.

Did you install the clutch disk the right way?

was the flywheel cut right?

your sure the freeplay is adjusted correctly?

let me know what you find and we can go from there.

I had the clutch installed by a mechanic, so I dont know. He told me he had installed these types of clutches before but who knows. Can there be damage done to the clutch disc if it were to be backwards??? And does it say on the disc what side is which?

Yes the flywheel was cut correctly.

And yes I adjusted the free play to be within spec.

Im going to pay a visit to my mechanic tomorrow.

Yeah I agree, im dont think I have that much power to overpower this disc.

thanks for getting back to me.

If the clutch is slipping now, more break in time will not make it get better or suddenly grab significantly better. The last 6 puck I put in a car was holding WOT (RX7 Turbo) stresses right out of the box (I couldnt help myself, lol).

You may be able to see something throught the inspection covers, or you may have to pull the trans again, but you have a problem that will NOT go away by leaving it alone longer.


EDIT: Im going to change that statement to "a problem that is UNLIKELY to go away..." After further thought I realized there are conditions that might make that happen, but in my opinion is unlikely.

even things like the step cut on the flywheel not being cut to the right depth can cause this problem.

Your basicaly BPU and like I said a stock clutch could hold that.

in to see what the mechanic says.

And this is the exact reason I ordered a flywheel with my new clutch from you...I don't trust others machine work LOL! I didn't want to deal with this same problem.

If you had it in backwords it probably would have made grinding noises the first time you pushed in the clutch pedal, or maybe it wouldn't even want to go into gear at all. If it's backwords, the springs hit the flywheel bolts. I'm just guessing on the 15% increase, it could be more but I would be VERY suprised if it was less then 15%, and as mentioned earlier, you wouldn't even be overpowering a completely stock clutch at 11-12psi on a ct26 (~300whp)
