clutch pedal looses pressure ( new HD zspeed slave )
I just had a new dual mass oem flywheel. Jwt clutch kit. And a heavy duty slave cylinder put in. Also my master cylinder got a rebuild kit. It's only 3 months old so I didn't replace it. And my pedal looses half its pressure and I have to pump it up and it will loose pressure again after pressing it down again . so it might have air in the system. Any input would be appreciative! Thanks

Well it said to change your master when putting in the heavy duty slave cylinder. And I replaced it brand new 3 months ago. And my mechanic did it all so I wasn't there. And when I picked up the car it seemed okay. But the next day I noticed it getting flimsier at the top of the pedal and my engagement slowly going down. And the rebuild is simply a spring and seal. Can't be that hard.

Rock auto. Just an oem one. But its always worked. So idk. Could have air . apparently the HD slaves are hard to bleed. And you have to bleed it several times. Idk what my mechanic did so

If it didn't come from the dealer it's not an OEM part. It may fit like an oem part, but not necessary function.
Certain parts you just don't want to use reman or third party. I remember the optispark unit in the camaro. After 2 non OE parts stranding me, I paid a bit more and with with a gm part. Never had a problem again.

If you're not losing any fluid then your master cylinder is probably the problem. I had a similar issue earlier this year where I kept losing pressure and had to pump it like 50 times to get pressure back but the following day, the pressure would be gone again. It turned out to be the master cylinder and ever since I replaced it, everything has been good. My thread is here.
I would recommend that you first re-bleed the system to ensure there's no air in the system. The best way to do this is to gravity bleed it. If the symptoms persist after verifying that you've removed the air from the system, I would replace the master cylinder with a new one vs a rebuild kit. If for some reason you decide to go with a rebuild kit again (really not advisable), I would at least buy an OEM kit just to remove all variables.
Good luck and let us know what happens.
