Bob, if you want peace of mind, overhaul the standard single master 
cylinder brake system in the whale from stem to stern, returning it to 
as-new condition throughout.  Then maintain it -- changing the fluid 
every two years, checking the system for leaks/rust/moisture annually, 
ad so on.

A perfect single master cylinder brake system worked fine when new and 
will work fine today if fully restored.

Too often, I see people fooling themselves by slapping dual master 
cylinders into vehicles that otherwise have old crappy brake systems.  
If you have any doubts about the efficacy of the conversion -- and you 
should -- then don't bother with the conversion and do EVERYTHING that 
the stock system needs.
