I'm pretty certain Norm Nock's book recommends against using the Mighty Vac on Healeys, though I don't remember that he provides an explanation. I have the full metal Might Vac kit, and it has not worked well on the brake system on my BN7. For that matter it wasn't the best choice for my Porsche 968, either. Further to Steve's offering of a source for a fitting that I understand will enable fitting a conventional Healey bleeder to the end of a spare flex brake line to create a remote bleeder I pose further questions since I assume Steve knows all of this. Does the flex brake line thread (24 TPI by 3/8") into the bleeder on the slave, and does the fitting pictured somehow attach to the other end of that line to take the fitting that has the capability to take a functional brake bleeder? It doesn't appear that claim is made for that fitting. Further to Steve's mention of the post I made a couple weeks ago, Clutch Pedal Went Away, I found the recommended OldPhartz bleeder was out of stock and ordered one I hoped would work from Summit Racing. I had to create my own connector to attach this bleeder at the bleed port on a new Moss clutch slave--fortunately I have the proper die and tubing to do that. But ultimately the purchased remote bleeder line seemed to leak like crazy--it has full rotational ability for the fittings at both ends of the flex line. I'm at a loss to know how that could not leak. So I'm back looking for a remote bleeder.
