When i first did my vacuum brake conversion i used a "T" fitting off the pcv hose / tube. My brakes wouldn't work very well setup like that. It was an vacuum related problem because the only thing i did was, this below.............
There must have been some other issue because the port on the TTA vac block and the PCV port share the same vacuum source?

Then you have a nice clean, 1 to 1 connection and a beefy szed port to plumb to.
Check out the pictures of the vacuum brake ported block from bweavy, Metco, Kirban's et al.
If you haven't already replaced your orignal plastic vacuum block, this would be a good time to do it and kill two birds with one stone, since the stock unit distorts over time and causes all sorts of nuisances.
I do still have the factory vacuum block so I will go ahead and order one of those billet ones tonight. Thanks!
