A 3/16" (0.191") brake line on my Honda rusted through from the outside

What should I watch for when I splice in a repair section with
double-lap flare fittings? Advice on the Net is contradictory and not
too helpful.

TIA -JSW

I wouldn't splice into the existing brake line, on the general principle
that if it broke once, it'll break again. If you can replace the whole
thing in sections, with all new pieces, yourself, without major
disassembly, then that's to be contemplated.

safety item = don't mess around
On Hondas and Toyotas it is not uncommon to see a perfectly solid
line rot out under a retaining clip (holds line to body) and the rest
of the line is perfect.. In this case, installing a short section can
be effective and perfectly acceptable. Just make sure the line IS
solid, and make sure you do a good jog ov double flaring the line, and
supporting the repaired section when you are done. Generally a good
idea to replace the entire run that is clipped to the floor - but you
can sometimes avoid having to do the twisties on the firewall and
around the rear suspension - or at least the twisties up on the
firewall/inner fender behind the engine.
