REFLECTOR:Cleveland Brakes

[KeithHallsten]

My understanding is that we are just trying to isolate the heat of the
brakes from the gear leg.  Therefore, the phenolic should be bedded in some
microglass onto the gear leg itself.

I have the Matco multi-plate internal brakes, which were originally designed
to dissipate heat primarily through the axle to a metal gear leg.
Therefore, I'm going to use a 3/16" thick aluminum plate "heat sink" and
combination "wheel fairing mount bracket" between the axle and the phenolic
board on the gear leg.  I'm not flying yet, so it remains to be seen how
well this will work.
