I bought a vacuum pump...what a waste of money. For me, it is only good for sucking out all the old fluid when you are changing lines, mc, and/or calipers. It took me forever to get the air out. I guess I could have been doing it wrong but it seems to me that I have much more control over everything when just doing the old fashion/manual method. I can do it in about 5mins and with much less brake fluid the manual way, and probably an hour with the damn vacuum pump.
op did you replace the bleeder valves? Is there thread tape on them?
