Thanks for the kind words James. Yes, the vacuum booster is what I referred to as the brake drum behind the master cylinder. Got that term from my dad when I was growing up, he also called the drums on the wheels “hub” drums. He loved his Pontiacs, had a ‘63 Catalina convertible that was stolen from in front of our house one night around 1967… the same light blue paint like your Tempest.
I do have plans for future articles and I very much appreciate the encouragement.
