Hey Guys.
I remember these gizmos from the '60's. The spring loaded plunger is
supposed to get pushed off it's seat by the pumping pressure and act as a
one way valve preventing air from being drawn back in during the up-stroke.
A tube and jar as usual could be used to catch the fluid, or not bother for
the 'messy' option. The biggest downside was that the plungers would
corrode and seize onto the seat, and the springs would rust solid, in less
than a year of regular motoring. Probably dissimilar metal reactions. They
had novelty appeal initially but proved to be junk with the word going round
very quickly to avoid them.

Subject: Automatic Bleeding Valves
I was going through a box of parts I brought home the other day that I had
bought for the BN2. In it I found a package with the name "Betta Parts,
Automatic A.B.V. Bleeding Valves". There are 6 in the pack with some
rudimentary instructions. This product is made in England, so I don't know
where or if they are still available in the U.S. They look like regular
bleeders with a removable spring loaded shaft with a seat on the end. The
instructions say to seat them fully and then on the line you are bleeding,
un-screw the bleeder one turn, then pump the brakes 5-6 times.
Remeber to refill the master every 3 pumps. I guess they seal after every
pump. From what it sounds like, this could get messy. They don't mention
attaching a tube to the bleeder into a jar. Anyone have any knowledge of
these bleeders? Anyone know the bleeder sizes for a 100-4? I have two
large bleeders and 4 smaller diameter bleeders in this package, so I'm not
sure what car they are for. I have not got to the brake part of the
restoration yet.
