so im still having that weird problem up top where it takes barely any effort to push down.

well i went to leave right now after just driving the car for 30 min and the clutch grabbed in the center and didnt have the play at the top. in the 2 miles i went to the store and back it was back to free play at the top and grabbing down low. WTF is up with my car? ive bled the clutch, its a brand new ls7 clutch in there, the slave was replaced may 2004. im so damn lost as to what the hell is going on. any ideas here?

I think that you can compensate for that stuff on an adjustable. I think that is where P Mack was going with that.

The reason I said that is when i had a Mcleod master it did pretty much the same thing a few weeks after installing it.

did it end up working itself out or did you have to adjust it?

P Mack

I ended up taking it out and putting a stock one back in. I'm gonna try to rebuild it and see if it works then.

thats kinda odd, this is a damn brand new 01-02 stocker, i hope its not messed up. it was working fine before AFAIK

so what EXACTLY was yours doing?

I just want to know why in the hell I have all the play which is inconsistent at the top of the pedal. I want to make sure my master is not a bad one. If I park the car the pedal is ok, when I get on the interstate and cruise, when I push the pedal in it will go about half way with barely any resistance. Makes me wonder if I have a POS master.

When i first got it, it would have no play at all and disengage near the top of pedal travel. After a few weeks i noticed that i could push the pedal in an inch or so before i could feel the resistance increased as the slave began compressing the clutch springs. It got worse quickly and the longer i drove the more play i would have where eventually there was little resistance until right off the floor and i barely had enough travel to disengage the clutch at all. If i parked the car for a while and drove again a few hours later it would be better for a little while but get worse every time i had to push in the clutch. Sometimes the clutch pedal would not come back up and i had to pick it up with my foot.

Your problem could be the master or the slave. I guess one thing you could try is disconnecting the quick disconnect hydraulic line and see if you can move the clutch pedal (gently).

ok so if i take off the line and easily push the pedal with my hand if it moves it means the master could be at fault? the slave is brand new as well, well not brand new but it is an updated one and has been on the car for quite some time. i may try to put my old master back in there and see if it works with that in there. this is just a big pita

Im in the same boat. Not suppose to use a shim and as far as I can tell all an adjustable master does is move the pedal position. Your master is only going to allow so much travel so adjusting it is just going to set your pedal height. Guess im gonna look at the PP and possibly shim the clutch. By the way if you disconnect the Quick disconnect line and push on the clutch pedal it should move a little but not all the way. If it goes to the floor your seals are bad in the master.

Yeah but don't push too hard cause you could blow something out.

WS6FirebirdTA00

iTrader: (33)

yeah i figured that much, just enough to tell if it has a leak. just some steady light pressure right? i mean the inconsistent feel is what i dont get. the pedal should catch close to the floor but sometimes it catches high after a long drive and then it will settle back down. if it were a pressure plate issue i would think it would act up some more. when i push the pedal down i can hear fluid kinda squirting inside of there. i did the drill mod to this as well as my other one i had, is there anything that could be related to doing that? i dont think there is, at all, but i dont see how a brand new one would fail on me like that

P Mack

iTrader: (6)

It could be related to the drill mod if you didn't get all the metal shavings out of the line and they scratched the master or slave bore.

WS6FirebirdTA00

iTrader: (33)

yeah i mean i flushed a lot of fluid through there but i was thinking maybe i didnt get it all out. how could it mess up the slave? the fluid just forces the sleeve out right? so there shouldnt be anything to leak down in there? should it?

WS6FirebirdTA00

iTrader: (33)

also, can you give an explaination on why it would be ok when the car was off but after im driving for a while why it gets odd feeling? that is the part that confuses the **** out of me. it does the same thing when the car is on or off just the PP is spinning when its on

Probably already said but check the routing of your clutch lines. If it is close to a header you are probably boiling the fluid which will give you a soft pedal after running for a little while and then hard again when its sitting. I routed mine out of the way and then had to shield it as well.

WS6FirebirdTA00

yeah i have it under the heat shield like it has always been, but i will double check that just to be sure. it is about the only thing that would make sense to why it had to deal with the car being on an off
