Master or Slave Cylinder

[Archaic2021]

So on my 91 chevy 5-speed I have lost clutch pressure.

 

Driving home the other night the clutch would not let me change gears. I had to pump it several several time to get pressure back. Once I did it drove fine.

 

I just put a new starter on so I was thinking I didn't get all the air back out of the Slave Cylinder so I started to bleed it again. For the next hour all I got was bubbly fluid. Same thing keeps re-occuring it will loose all pressure then I can pump it up and get it back but literally after a minute all the pressure goes back out until I pump it up again.

 

No fluid leaks of any kind that I can see. Does this sound like a bad slave or master cylinder for the clutch?

the master has a means to recycle if bad, like a brake master cylinder.

slave side would leak being bad.

 

No leaks, I'd go with master.
