Brake line flare: Bubble or double?
Hi guys,
I am redoing the brake lines on the 2002 Excursion. I have yet to take them apart, but are the flares bubble or double?
Doing brake lines for the first time and buying the rust proof copper nickel lines.
Thanks

I've yet to see a USA brake line that's not double flared! Every Google search I've done says the bubble flares are acceptable for everything BUT hydraulic lines.
It seems the bubble flare is acceptable with the special backing nuts but even so with the long time common use of double flared brake line and its more than acceptable performance I'd not be looking to reinvent something so successful for at least 70 years.

They don't sell a 15' section that runs from the front to the rear.

Since the invention of hydraulic brakes. With the master cyclinder in the engine compartment, how do you think rear brakes are activated??

Note to self...when working underhood, do not refer to this area as the front of the vehicle. Begin to refer to it as the rear. Enjoy the look of consternation on peoples' faces right before they call me an a-hole.
Anyway, to neilc88...enjoy that copper-nickel line! We sell a bunch of it where I work, and just last week I made new trans cooler lines for my dad's Excursion...it worked like a charm. Easy to bend, and easy to flare. I never double-flared anything before in my life, and this stuff made me look like I was born with a flaring tool in my hand.
Just make sure you have a GOOD, quality flaring tool. I ended up using a KD #2199 that I borrowed from a techie buddy, after it was obvious the Chinese tool I got at Advance (I know...I know) was a total POS.
Good luck...

Pat you've never double flared even brake lines? I've always been told and used the double flare myself---can't recall anyone not doing it. Would be interested to know if it works just as well.
