Ok im going to make this as detailed as possible so someone can help me diagnose this issue im having

Over the course of 1 week ive been slowly losing clutch pedal pressure till 2 days ago when I lost it completely...It first started out with having a spongy clutch at start up and then once the car was at normal operating temp clutch was firm and working normally...the clutch pedal stayed like that till the last couple days when it would just sink to the floor at startup and eventually gain pressure after driving for a while...and now its just gone.

I replaced the CMC when i first got the car less than a year ago...no signs of leaking inside the car or outside to this day.

I just replaced the CSC less than 3 hours ago assuming it had a leak and was leading to air getting into the lines

After putting in the new CSC me and a buddy bled the lines for what seemed like an eternity...end of story is there was always air in the lines and the pedal wouldn't come up. As far as I see there are no leaks in the CSC, CMC, or any of the connecting lines.

Has anybody had any issues like this? Ive tried searching various forums and can't find much info...my best guess is that im going to have to replace the clutch

btw to my knowledge it has a XTD Stage 3 clutch
