I am having issues with my hydraulic clutch in a 94 probe gt. I've replaced both the slave and master cylinder, and bleed it until pure fresh fluid has come out, and it's still mushy and doesn't work properly. The last thing I can think of is that it's the line itself? Any help appreciated

 

Usually a mushy operation is due to air trapped in the system.
What was the original problem?
Sometimes , the air will rise up into the master and eventually go out, but if it is trapped, can't move, it will stay and has to be removed through bleeding.

 

One day I was driving and I pushed in the clutch and it didn't come back up.And I have bleed almost an entire bottle of fluid through it.
