Any
takers?

You could use a more modern hydraulic fluid rather than car brake fluid.
Even the old 5606 has a prety high flash point. Silicone brake fluid has
far less a problem but requires more master cylinder volume to over come the
spongy feel, and is thick and difficult to bleed. I use aftermarket Wilwood or
Lockheed 570 to 600 degree wet boiling point race fluids. Never a problem even
with the Carbon Metalic brake pads that flash the rotors to orange when cycled.
Most small calipers are sliders. Where there is a single piston pushing
from only one side of the rotor. These calipers move when operated and
there must be an accomodation for that movement in the mounting system. A
single aluminum line all the way into the caliper will fail close to the caliper
fitting.
Also the flex of a spring gear would add quite a bit of relative movement
between the line and caliper. If the gear leg is rigid it needs only a short
flex line right next to the caliper. If it can flex at the fuselage it needs one
there also.
A length of dash 3 the whole length of the leg would be hard to beat for
reliability. However adding flex line adds to spongy feel as well.
I run short flex lines in dash 4 to both rear calipers (4 2.00
inch pistons each) because even though these are rigidly mounted they still
flex a bit and would fatigue a rigid brake line.
