15/16” will give you a long pedal travel with a slightly spongy pedal feel. I have one in my Barracuda now and I’m switching it out to 1 1/16”
My Dart has Wilwood rears and Strange front brakes. When the factory non power, drum brake MC went bad I installed either a 1 1/16 or a 1 1/8" bore MC on the car. The first time I drove it when I got to the end of my driveway I had both feet on the brake pedal and both hands on the wheel to stop it. That afternoon I ordered a 15/16" bore MC from Cass. I would like to try a 7/8" bore on it as the car has never stopped as well as I'd like it to since I removed the factory iron MC.
