Default Need Help By 5pm.. Slave, or master!?!?

ok here is the deal.. my car will drive normally at all RPMs under 4500. If I shift at 5k or higher my pedal hits the floor, and keeping me out of all gears.

if i downshift to quickly my pedal hits the floor, and clutch wont dissengage fully with the pedal on the ground, but still in gear.

In order to get pedal back, i have to pump it.. or leave it alone till it builds pressure again. Im NOT losing any fluid out of my resivour

do i need to replace the master or slave..


Master, Slave, and LS7 clutch just went in approx 20k ago...

Drill mod, or adjustable master. I vote adjustable master, that's what i'll be doing very shortly along with new slave and clutch.

forgot to mention, drill mod has been done already.

the other issue is, if i put my foot on the pedal right before i shift at high RPM, i can physically feel the pedal pick my foot up, then no pressure at all.

You're gonna have to check both the master & the slave.

so nothing got done... need have some good input here.. i bought an oe 02 slave, just waiting to see what ppl say before i do the job. its not to late to take it back, but an oe master would end in the same results. so id need to purchase and aftermarket one correct? or where there provisions to the 01-02 master as well?

I know I might catch some flack for this but with that LS7 clutch in there your def going to need a tick master. I ran a ls7, stock master, and a 02 slave for about the same milage with no issues at all. Then in the upper rpms it would seem to shift ok but apperently I dont think it was fully disengaging and it ended up ruining my 2nd gear on my tranny.

Even though alot of people use the ls7s and dont have any problems they are still a heavy clutch and the f-body hydraulics cant fully disengage them like the ZO6s hydraulics... Just my .02

ajustable master only give the place where the clutch is disengage



a master in bad condiccion no necessarily leak....it can introduce air in the system that can be a cause of this
try bleding again and see

if dont get better.... slave or even can be the press
