First a little history of the problem. About a month ago I was having difficulty shifting and the clutch pedal felt soft. (Clutch and all related parts were replaced one year ago) I looked at the slave and master cylinder boots for leakage and found the master cylinder leaking. I replaced it and all was well for a month, till pedal felt soft again and was hard to shift. This time the slave was leaking. Replaced that and back to the same problem after only a week.

Bleeding the system stiffens the pedal some but it isnt right. My question is on the bleeding. If I gravity bleed, the pedal feels the best but it is not totally there. If I have someone push the pedal like you would do on brakes, I can never get the air out. The clutch is unusable this way. Gravity bleeding gets the best results but if feels like there is some air in the system still. Is it possible for the master cylnder to have an internal leak or something and let air in the system?

Thanks
