I found this in surfing the web at a site for another type
of airplane.
"First of all, NYLON lines must never be stored where
they get exposed to direct sunlight. An excellent idea
would be to store your roll of brake line in a black plastic
bag until you are ready to install it. After it is installed,
paint it with black or silver paint. Do not roll it out into
the sunlight without wheel pants or paint to protect it.
Heat can soften the Nylaflow and allow it to expand
under pressure, and possibly even burst if the heat is
excessive. For this reason, it is very important to route
the brake lines as far as possible from the brake disc.
Keep in mind that under heavy breaking the disc can
get very, very hot. .....In addition we strongly recommend
insulating the brake line with fiberfrax. We cut a long
narrow strip, perhaps 5/8" wide, applied silicone to the
fiberfrax and wound it around and around the brake line
until it was covered from where it appeared out of the
trailing edge of the strut to the nut on the fitting on the
caliper. A little tape will hold it in place, slip a piece of
heat shrink tubing over the whole thing and shrink it
down onto the fiberfrax. We also wrap this in aluminum
foil, which of course helps by reflecting any radiated heat."
Some things to do might be:
-Take the Nylaflow out of the clear plastic bag it is shipped
in and store it in a black plastic bag until it is needed.
(It is attacked by light and ozone)
-Try to have a short section from the wheel wells to
the puck that gets replaced at annual. (Or just replace
all brake lines annually.)
-Think about insulating and protecting from light and
ozone once installed.
-Carry a sand bag and rope to throw out and drag if
the brakes fail.
