My slave cylinder is losing pressure while I have the clutch pedal all the way down

hello. I need some help diagnosing a problem with the clutch hydraulic system, I have a base model 1995 first gen and I have already replaced the clutch, and the slave cylinder but not the master clutch slave cylinder which I think is the container which holds the brake fluid for the slave cylinder, i'm not no mechanic so I don't know the exact name for it lol. but basically I will press down on the clutch which disengages the clutch but if the vehicle is off you can actually hear the slave cylinder slowly lose pressure and engage the clutch (while I still have my foot down) so whenever I put it in first and let off even a little bit it jolts me forward and it makes me start going. The worst thing is when I'm just trying to move forward a little bit, I cant. If i let off even a little bit to get going it fully engages the clutch and when I press back down it doesn't disengage the clutch so I have to let off fully then press back down to get it back in neutral or else it stays in gear. Again, I have replaced the clutch and clutch release plate, I have bled the system multiple times and completely emptied the fluid and refilled it along with bleeding it after that, any help on diagnosing this problem would help tremendously, thanks.

 

You’d be seeing brake fluid corrosion (clutch system uses brake fluid) if it was leaking anywhere out of the system. Likely if you’re not, it could be leaking back into the reservoir on top of the master cylinder.

 

So should I replace the clutch master cylinder?

 

yes , replace the clutch master cylinder

 

Okay, thank you so much
