78 Guzzi T3.... Been bleeding on it for a few days now, read a lot of helpful stuff on line and in Guzziology. Even tried to follow a good bit of it, although not all (I really don't want to do a full bench bleed, nor have I removed calipers and hung them up in the air). So I thought I'd ask a few dummy questions and see if that gets me a little further along. I have the rear calipers acting like they're bled ok, I have speed bleeders on them, and getting flow with no bubbles when I crack them. Que's: 1. If I yank the bleed nipple, does that by itself introduce any air I should worry about? 2. On the front nipple (std, not a speed bleeder), using the MityVac to apply a vacuum, if I crack it I get a lot of bubbles, but I think they're just coming the threads of the bleed nipple, how do I tell? 3. I tried to bleed some intermediate connections, opened them and got some brake fluid out into a rag, how do I tell if there's still air there? 4. Bleeding the master cyl...duh I cracked open the banjo connection, got some flow. same question as above. 5. Assume a mityvac really isn't to use with a speed bleeder, ie won't generate enough pressure, right?
