Need help with a clutch problem!!

I would change the Master Cylinder anyway, you can do it yourself. I feel for you having gone thru so much at the hands of others. Find a friend that can help and save yourself some money. It's always recommended here on the forums to change Master Cylinder anytime the slave is changed, they both have the same amount of cycles on them, it stands to reason one is just as worn as the other.
Besides, bleeding is the worst part and if the slave is changed, gotta bleed anyway.
