<VV> Brake bleeder

[Chris C, Warwick RI]

Motherday is over.  Sufficient sucking up, hoping to hit the treasure trove 
of small auto tools.

I am thinking a presure brake bleeder.  Hoping for one that will work with 
the vairs, and one that will work with the modern cars (caravan, 84 caddy 
etc).  Have a 1 man bleeder now, but would like to upgrade.

Or a uni-sync.   Never having seen one, what does it give me that using a 
the carb balancing tool from the basics book does not.

Thanks for the advice.
