[Spridgets] 78 dual brake master cylinder

[Guy R Day]

You are playing with your brakes, you know, the things that save you butt 
when come up to a stop light or are barrelling too fast into a corner.  But 
hey, and it may be a selfish way of looking at it,  the good thing is it is 
your butt and not mine.  Or perhaps, your wife's....

Seriously Karl, I'd want the brakes about right.  I'll stand a little fuel 
starvation at high revs, tickover being a little lumpy, the heater burning 
my feet but brakes, well I like those to work properly.

All the best,

Guy R Day
