What is its purpose?
I'm guessing it's for protection against rub-through holes caused by vibraton where the line touches the surface it's running next to?
I got to thinking about this as I'm replacing some rusted brake lines with parts store line, and it of course, has no wire coiled around it.
 
I assume the same thing for protection. May also make the tube stiffer in that location and less probe to work hardening do to vibration.

IIRC many venders sell OEM style replacement lines already bent to fit. Might be pricier.
 
External wire also good for easier bends (less chance of kinking) but, on the downside, more dirt, etc. can accumulate over the years and with added moisture - - - you should know the eventual results.
 
It's on the brake lines (tubes) as a rock guard, dampens vibration, and to keep the tube from collapsing when bending.
 
It has nothing to do with the bending. I work in a place that makes tube assemblies for agriculture and mining companies. This is a rock gaurd only. We have this stuff in stock.
 
cheap wire benders usually come with a few coils of spring looking sheathing. Use it to slide over a section and bend it by hand. As stated it prevents the tube from kinking when you bend it. OEM's didnt use it for that reason.

I would take it from the houses mouth, and make arrangements to buy some

I wire brushed mine , still on the stock brake lines and reused them before putting the end fittings on and double flaring them .
Dam sure didnt use them to bend the new lines !
 
Gravel guard only as stated above. You can buy it and slip it over new line and just have to re flair it.
 
In vehicles, That extra tubing length with wire wind is only found right at master cylinder. Its a heat sink to cool the fluid, protecting the master cylinder.
 
I think the wire helps to transmit the signal to the Aliens, So they can enjoy seeing a few Kool Mopars..........:thumbsup:
 
Its called armour. And thats all it is. To protect it. Nothing more.

I have always heard it called gravel guard or armor. Its simply to protect the line in vulnerable areas such as near the wheels and anywhere where the line can rub.
 
I only thought of this now, at age 61, lol. But I'm only replacing a couple sections that had it originally. My car now has subframe connectors and I ran the front to rear line partially in the front wheel well. I shielded that with a heavy sheetmetal guard.
It looks cool, and hopefully will still attract aliens.
:D
 
A lot of new cars actually have plastic extruded over the steel brake lines for protection, both from corrosion and wear, abrasion, impacts, etc. I have several customers that do this in Michigan. First time I saw it, it threw me for a loop, as I thought the whole line was plastic!

We have some customers that require some tubing similiar to that. It has like a nylon-ish coating on it, the tubing with it we order is called procoat.
