Stage 3 Clutch Problem -Help-

[SC06SI4U2NV]

Well I just installed the clutch masters stage 3 clutch and pressure plate and I had the stock fly wheel resurfaced.you can see this post i posted during the install Its That time, Comptech+Slicks=Poor Clutch. Every thing during the install went along fine; every thing lined right up went right in and so on. So I start the car up in neutral, press in the clutch pedal and try to put it in gear and it won’t go in any gear so I give the pedal a few pumps and it goes in gear. So I bleed the hydraulic line again thinking it just has air in it which it did and I try it again and it work goes in gear fine so I take it for a spin and right away it started to get hard to shift and it got harder and harder so I pull back in the drive way check the shifter linkage and it fine so I figured ill bleed it some more just to make sure. And it still did it, so I was sitting in the car holding the clutch pedal down for about 30 seconds then tried to put it in gear and it was really hard to get in and when it when in it felt like the clutch was trying to grab with the clutch pedal all the way to the floor. So I take it out of gear and give it some pumps and it goes right in like normal. so im holding it there for about 30 seconds and it feel like the clutch is starting to grab again with the pedal still to the floor.

So basically there is no air in the lines I went over it 100 times. What it seems like to me is that the stock slave cylinder can’t hold the stage 3 pressure plate down. It is releasing it at first but then it seems like its starting to back off. Or having the fly wheel resurfaced caused the pressure plate and clutch assembly to move forward that tiny bit and the pivot arm does not have the little extra throw but I don’t think its that. So why would it work if you pump it?? Could the slave not be able to hold that amount a pressure down?? I know there are guys on here running stage 4 clutches and pressure plates with the AJP kit. I just don’t want to pull it all back out again and it be hydraulic related any Ideas??

Either its something with the throwout bearing or you should replace the flywheel also. Who did the job?

[projectprelude]

i would get an aftermarket flywheel or a new one

[SC06SI4U2NV]

i did the job and i put a new throw out bearing in and i had the flywheel resurfaced they basicly cut it like they do brakes

[honda06si]

its not the slave cylinder, i have a stage 4.

[honda06si]

i know youve probably checked everything but it seems there is a leak somewhere, this same thing happened to my buddies jeep and we found a leak in one of the lines...

it might not be the fitting that connects to the slave cylinder, and hell you might not have even touched any lines, but go back and look again because when you were lowering the tranny or something, you could have hit one

thats my only guess

[SC06SI4U2NV]

so you think it is doing this because the flywheel was resurfaced?? i was thinking that was the problem at first but they only take off like a 30second of an inch barely anything

[honda06si]

no its not the flywheel. people have them resurfaced all the time

[SC06SI4U2NV]

yea im gonna go triple check every thing

have others installed installed aftermarket clutches w 8thgen si flywheel.

remeber reading somewhere that u must use a dc5 flywheel w some aftermarket clutches.

[jay3151]

maybe i miss read somthing

Definitely air in the line or a leak. Bleed and bleed again till your leg is sore.

[SC06SI4U2NV]

alright well i just pulled the slave out just to make sure there wasnt any leaks there and checked all the lines and bled it again and it still is happening

[honda06si]

what kind of fluid did you use?

and not to sound like a dick but do you know the proper way to bleed it?

[SC06SI4U2NV]

i am using prestone DOT3. and as for bleeding it i take the cap off have some one pump the pedal a few time and hold then i crack the nipple valve let some fluid out shut it and keep repeating it until the pedal gets hard. now is the a different way cuz on my 300zx there is to spots you have to bleed but i did not see another place.

[SC06SI4U2NV]

i do have some ATE super blue DOT4 i dont think that would make a difference

Correct me if I'm wrong anyone, but I believe the most effective way to bleed is to leave clutch all the way out, open bleed screw, have someone push clutch to the floor, and close bleed screw as soon as the clutch hits the floor, and repeat. Try that maybe? Hope it helps.

Edit: leave filler cap off just so that you can keep replacing lost fluid as the level goes down.

did you ask how much material the cut off your flywheel. in most cases using a cookie disc is more than enough to clean a flywheel for a new disc. if they cut too much off your flywheel you might have an issue.

also why did you need to bleed the clutch in the first place did you disconnect the lines during install?

next the pressure plate should not be your issue that CM Stage 3 uses a pretty light pressure plate usiually around 1900-2000 lbs of pressure
