[s-cars] Confirmed: Braided brake lines don't age well

[Theodore Chen]

in that case, i'd wonder if there was an issue with your car that caused
it to pop a braided steel hose and a rubber hose.

a lot of mechanics allow the caliper to dangle from the hose after removing
the caliper.  rubber hoses will put up with that kind of abuse better
than braided steel hoses, but it's still a very bad idea.  it puts a lot
of stress on the hose near the fitting, and in the case of braided steel
hose, it causes the teflon liner to cold-flow, weakening the liner.  it
can also damage the braided steel.

years ago, i took my mustang to a shop to have a torsen differential
installed.  i saw the rear calipers dangling from the braided steel
hoses.  after complaining to the shop, i changed the hoses immediately
afterwards.
