Stupid question - master cylinder bore sizes
I'm thinking about replacing my master cylinder with one that has a slightly larger bore. After installing a larger SN95 booster on my car I've found the pedal is now too light, so I think I want to try a larger bore MC to try to get some pedal feel back. I currently have the "stock" Baer MC, which I'm pretty sure is 15/16". How do I confirm that? Where does one measure the bore size? Do I need to remove the MC to do the measurement, or is the measurement taken on the outside of the body of the master cylinder?
Also, any recommendations on whether I should try a 1" or 1-1/16"? How much of a difference does the change in bore size make when it comes to pedal feel?
