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.

Jepson "technically classified Dot 4" is the scary part. From
Matco's website:
"
Mil-H-5606 aircraft hydraulic fluid or compatible fluids are
reccomended.
DOT5 may be used but not
DOT5.1 which contains glycol.
DOT3 and
DOT4 may not be used and will cause immediate damage to the seals."
It's the
technicallities that will cause the immediate damage 8*) Are we reduced to ordering some extra seals when we order the brakes so that we can run a soak test for a few months before actually filling the brakes? I just ordered one of their
MC-4 master
cyclinders. I'd hate to ruin it right off the bat.
