Braided line is an improvement over the rubber line used between the
frame and the axle, partly because the typical stainless braid over teflon
expands less when pressure is applied, and the rest because teflon and
stainless steel don't deteriorate the way rubber does.
However braided line is less than ideal for replacing the rigid hard lines.
Because the braided lines while stiffer under pressure application than
the rubber soft line is (unsuprisingly) more prone to expansion than rigid metal line.
As I was doing a complete mechanical restoration of my truck last
year I replaced every inch of hardline on my truck, Except the tubes on the axle,
with 3/16" stainless steel hardline (having metal lines rust out is "annoying")
I didn't replace the rigid lines for several reasons;
first I had two sets of NEW factory Ford pre-bent lines
for my 8.8" axle.
Second I'm planning on switching to an Explorer axle (31-spline!)
and third I was running out of 3/16" stainless steel rigid line.
