Ernest,
I find the need for the combustible fluid so repugnant that I will probably fit auto or motorcycle components if I need to. Otherwise I would  change ALL the seals provided. I will NOT run that combustible CRAP in my plane. I can get components from so many different manufacturers that this is ridiculous. I will not endanger my aircraft by a small fluid leak. I will plumb the entire system AN so I doubt I'll have a problem, but I won't take a chance. Small calipers are available from, Brembo, Lockheed/AP, Wilwood, Tokico, Nissin, and more. There are better brakes on any go-kart than most planes sorry to say.
