Too much rust on brake line?

I'd give it 5 minutes to break that line free but not waste time on it. Just cut the line and replace the hose, cheaper than paying for labor on something that probably is going to be damaged anyways.
 
Like you say, this is a tough area to treat with oil based rust proofing products because of the turbulence and wheel wash. Woolwax is a better option than FF for those, but still needs re-sprays.
I like to coat the 'bare' brake lines (at caliper) with cosmoline.
It does NOT wash off and will NOT creep any closer to brake pads.
I take a small brush and also coat the rubber-hose connectors and caliper bolts.
 
Ha! fair point. At the moment, I can't take it down, as I have 3 vehicles for 4 drivers going 4 directions some days of the week. Car pooling is plausible, but at some point, it becomes too painful.

For having a brake repair (or any repair), the daughter can drop the car off at the garage as it's literally across the street from her high school, and pick up at end of school day (if all the stars align).
If your teenage daughter is going to drive the CR-V, please have it repaired immediately. If I recall correctly, didn't she flip and total a Camry on ice a year or two ago? Don't take any unnecessary risk, especially when your family is involved.

If you want to take a stab at repairing it yourself, I would suggest cutting the metal line just above the rusted section, then removing the lower section and rubber hose (destructively, if required). That would prevent the good upper section of the metal line from being damaged as described in Post #2.
 
Most shops will likely insist on replacing the entire line from the proportioning valve to the flexible line because added junctions increase propensity for leaks.

I know you don't want to flare on your own. Got it. Instead, measure (with a string) the entire length of that line from its origin to the brake hose junction. Buy a piece of Ni-Cop replacement line as close to that size as possible. Bend as required and install it yourself. Ni-Cop is easily bent and resists kinking. Some people even bend it by hand. I usually find a small cylindrical object (like a spray paint can) as a bending aid.

If the new line is too long, you might need an extra bend or two, but replacing the whole line is a pretty easy endeavor.
 
I’d swap that.

MB allows one coupling in the line. I used copper nickel line and used SS armor. I probably have more SS armor than I’ll ever need so let me know if you want a length.

Wasn't expecting this thread to pop up on me... I should look at it, it's been a year, so it's probably worse now. Something else for the to-do list today.

Daughter no longer drives it, but son still does, so no change I guess, neither can deal with a brake failure.
 
The copper nickel line is easy to work with, and I don't think its hard to flare? My buddy made it look easy and he's not a pro and doesn't do brake lines often.
