Hi everyone. I'm Eric and have a 1959 Dynamic 88. I'm about to put on a disc brake kit from Scarebird and they recommend a dual master cylinder. Has anyone made that upgrade? If yes, what master did you use? Thanks.

Welcome to the site. I moved your question to the brakes forum. Post a proper intro in the Newbie section with pictures when you get a chance.

 

Welcome. The better question is, what M/C does the manufacturer of the kit recommend? M/C bore diameter is important, but depends on the specifics of the calipers used.
