Replaced clutch line and bled system; why does the clutch still 'fade'?
#1

So, I'm still unfamiliar with the whole clutch assembly and how it all works, but, I replaced my leaky clutch line with a SS CS line and it still wants to go to the floor...
It's drivable, it's just I have to 'preemptively' pump the pedal before shifting. I also can't just 'rest' my foot on the pedal, or it will just go to the floor...
But yeah, the system has been bled several times, and the problem has still persisted.
Any suggestions on what needs to be replaced, or what the suspect part could be?
Thanks,

Could be air in the system, but it could also be a bad master or slave cylinder. If they fail internally, the fluid gets past the primary seal/piston, resulting in a lack of pressure. You would not see any exteranl leaks when this happens. It's a good idea to replace the entire hydraulic system for the clutch if any part needs replacement. Under $100 for all 3 components.

Pics or descriptions would be oh-so-kind.
Hmmm... Does it have to do with the little 'pedal' thingy that engages with the clutch, that the hydraulic line 'plugs' into?
Thanks,

My write up of changing master and slave cylinders...
https://www.rx7club.com/showthread.p...1&page=1&pp=15
My write up is the 12th post down, or the 7th one past yours. It's the really long post.
Wait a second you know where the Master cylinder is. It's the one you put your fluid into.
Also I believe that you could use an N/A's slave and Master to replace it but why not just get new one's unless your N/A is your parts car. Don't quote me on them being compatible though.

I'll try the swap from my N/A and post back with the results.
Thanks a lot guys,

I rebuilt both of mine for 15 bucks (total). I got the kits from Oreilly Auto Parts. There's only a couple of parts in there. Just clean out the cylider real good, and get it smooth. A brake hone would be good, but I used 1000 grit sandpaper with a little brake fluid as lube. It worked fine. I've been driving it for 6 months, no problems. The whole job takes about an hour. Bleeding it is the hardest part (by yourself). If you bench bleed it, it's not bad though. Good luck

Alright, thanks a lot guys. The problem actually turned out to be a bad Master Cylinder. It had a leak in it somewhere.
I also re-lubed the Slave cylinder with white lithium grease because it was kind of sticky. So yeah, success! I got the system bled and everything's awesome.
Thanks for the help and suggestions!
