Teflon tape is a good idea. I have to wonder, though, if the brake fluid breaks the tape down over time, since it's a corrosive. I guess removing the bleeder screw is okay as long as no one is near the pedal to be able to suck in air, and the MC never runs dry. The old mechanic in the auto craft shop I use told me that emptying the master cylinder will put air in the system as well, even though I filled with with fresh fluid. It was the first thing I did- no bleeder screws were open- so I don't see how this is possible. I was getting lots of bubbles using the vacuum bleeder, but I think that was the hose adapter letting air in around it. Air was getting in there somehow, because I was hearing the vaccum pump sucking in air as I squeezed it. This whole thing just seems like it should have been easier and more straightforward than it was. I did get a lot of old black fluid out of the rear drums, though. Still have to get the front calipers flushed, so I'm doing it again today the old fashioned way- someone in the vehicle manning the brake pedal. Messy but effective. Is this vacuum bleeder even working correctly? I'd like to think I can still use it, but not with the hose attachments they've provided. Who has one of these and has used it on their van???
