My clutch pedal felt funny today so I decide to hook up the mighty vac to it and bleed it to see if it would help. Ive done this before after installing the clutch but now no matter how long I bleed it, bubbles keep coming? Is this a sign of a bad slave or master cylinder? I dont see any leaks anywhere but it seems like its sucking air in from somewhere. Ill about think I have it bleed out and then up pops a big bubble.

 

Mine did that for hours. I think it was just sucking IN air instead of bleeding the system. Do it how GM says to do it, easier and it works.

 

I never had this problem before, it always stopped. Hows GM recommend it, by doing the slave by hand?
