Master cylinder bore size?
Im having problems with my brakes and my master cylinder. I have wilwood disk brakes on the front already and was looking at wilwood master cylinders and the have different bore size. I watched the video from summit racing about the different sizes and what they mean I just don't know which one i need. So my set up is power brakes wilwood 4 piston disk with a 8in out of a 67 with a I6 so my options are 7/8" 1" and 1.12" so which one be the best for my set up and why?
