For all I know, the buyer is still using those = lines. 
 
It is possible that unsupported line= s flop around in the wind when the gear is out and the line is weakened at the brake-to-line fitting

Using Nyflow for brakes is k= inda creepy for me...

Chris--

I'll be using the synthetic MIL-PRF-83282 bra= ke fluid. It has a "Fire Point" of 490=BA F, as compared to 360=BA F (?) with th= e 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 of= f the runway, his plastic brake line melted and the 5606 hit is brake disk.
