[s-cars] Rear brake line failure....

[Tony Curran]

So what's the recommended service window and what to do to very they're in
one piece? I will be replacing the front ones with the BB upgrade happening
soon. Should I just replace the rears too.

I can verify the lines are

Not too tight.
No over bend to create kink.
I don't cook brakes (no track events).
I don't drive the fluid to boiling point.
Flush and replace every two years.

What else to do?

Visual inspections on SS lines are a false security; they can and will fail
from a kink/too tight a bend, or the slightest nick or scarring of the
plastic tube.  You cannot see the line underneath the SS cover.  Jackets
over the SS help with keeping dirt out (which gets between the SS braid and
the plastic line, then abrades it) but aren't the end-all.

More importantly, stock lines will *usually* fail developing a small leak as
Jim's GF found.  A teflon line will *burst completely*, resulting in
*complete* loss of braking.

Result?  Skip down about half-way:

That line (notice the jacket and the brand?) came completely apart while the
owner was doing a buck-plus down the main straight at WG.
