Dear EditoR
The plastic air lInes on our
M871A2 traIlers cross over and
touch resistors ±n the trailer's
nose box.
The heat from these resistors
melts the plastic² This creates
air leaks which lock up the
brakes.
We protect the air lines by ³n-
sulating them with rubber hose
where they cross over the resis-
tors² We use ´µin x 16¶in hose.
