bleeding the lines is about the onlything you can do unless you want to change the slave cylinder or the pump thingy. i can't remember what its called right off hand.

but to bleed it, you're gonna need like a 8mm(i think). pump the clutch till it builds pressure, then on the SC should be this little thing you can turn with the 8mm(its gonna be on the end of the cylinder). turn it just enough till the fluid starts coming out. tighten it back up and do it again, till all the air is out of the line. and only way i know to tell all the air is out, if is you do it a couple times and you're getting nothing but fluid.
