Is that a different adapter than the universal that people complain about on Honda's?
Brake bleeding can be easy, and some times it's a PITA. My Volvo is a PITA because it has a brake junction design, which is an excellent design because when one brake leaks or what ever you still have three left. But on the other hand, it seems like one air bubble or two can be problematic.
The crowd over at Turbobricks recommend the Motive bleeders because they pressure bleed as already mentioned by The Critic. The Mityvac can suck air back in the system when the bleeder valve is open. There may be a work around, but I don't know about it.
Anyway, I am going to buy a Motive bleeder myself because it just seems to be a better method especially if you get a good seal on the master cylinder.
