Hey guys, this is kind of a continuation of a previous topic on my buddies '66 Newport, all drums. The brake pedal is super sensitive and will lock up the wheels with almost no effort. Many suggested the booster was bad, and it seems to be that way. This car still has the stock single master on it and we'd like to do the dual conversion since we're under the hood anyway. Its my understanding that the '67 master and booster will bolt up directly, and just leave me with some new lines to be made, not a problem at all. I was going to source the parts from Rockauto, with Cardone part numbers #503520 or #506121. The only difference is one is listed "without Field installed Hydro-Vac", and the other "with Field installed Hydro-Vac". From what Google is telling me, Hydro-Vac was a dealer installed option to help with stopping. I'm assuming this car doesn't have it since its a '66, so I would want #503520 (without), correct?? I first had called Prior Brake (listed in the directory) for rebuild option and was quoted $150 plus the core cost of the dual master, and they didn't have one in stock. This car is going to Hershey Oct 12th so I figured I could just buy it all for cheaper and get it quicker since there's no turn-around.
