I think the big problem is the plastic/rubber hose.  You really don't want it to fail on landing when you are really trying to stop.  I believe a Lancair brake line failed somewhere in Oregon, airplane went off the runway and smashed into a tree, killed everyone.

Using Nyflow for brakes is kinda creepy for me...

Chris--

I'll be using the synthetic MIL-PRF-83282 brake fluid. It has a "Fire Point" of 490º F, as compared to 360º F (?) with the standard MIL-PRF-5606. The synthetic is approved for use with BUNA-N.

John,
That could have been ugly.  A friend of mine with a Glasair had a rejected takeoff on a short runway.  As he turned off the runway, his plastic brake line melted and the 5606 hit is brake disk.
