I'm working on my '93 G20 and cannot bleed the air out of my brake lines to save my life (literally). I know this page says not to use power bleeders: http://www.sentra.net/tech/garage/brakes.php#Bleeding%20brakes But Motive says their product works well. How do I keep from reintroducing air into my brake system? Should I just do it manually? Thanks. ===== '92 black SE-R '83 BMW 320i
