Kerscher tandem master cylinder bore size

[Tim]

Thanks Wally,
I am planning to use Wilwood calipers - 4 pot 44.5mm in the front and 4 pot 35mm at the rear. Do you think the Kerscher m/c with 23.64mm will match? I will use proportioning valve to bias the front and rear. My original plan was to use racing pedals system such as Tilton but it is far too expensive. If the Kerscher m/c can do the job, I can save a lot for other parts.
