This is what I did to fix it:
Replacing sections of solid lines (brake lines in this case)
To do this you will need:
-lengths of 3/16" metal brake line (I used 3 5' sections to replace the majority of both front - back brake lines)
-2 3/16" inverted flare fittings per line (will be female-female, looks like a long nut with a ridge through the middle on the inside)
-4 3/16" flare nuts per line - 2 should come with the brake line
-mini pipe cutter
-mini pipe bending tool
-double flaring kit
Steps:
1. Cut bad pipe off from car with the cutter. Make sure to leave about a 2" section of straight, good line attached to the car.
2. Slide a flare nut all the way down the line to one side, make sure the threads are against the flare and not the hex.
3. Starting at one flared end of new line, bend to match the section of old line and trim excess length if necessary. Double check that there are no bends between the flare nut and the flare at the starting end of the line.
(Any bends in the line will make it very difficult, if not impossible, to move the flare nut along the line. The only solution is to cut the line so the flare nut can be removed, then starting again)
Leave about a 2" minimum straight section at the end of the new line. If bends are necessary past this section, continue to step 4 and return back to it after step 5 is complete.
4. Slide a second flare nut over the end of the new line, with the threads closer than the hex to the end. The two hex sections of the flare nuts on one line should be "facing" each other, like this: \\\\H========H\\\\
5. Use the double flaring tool to flare the cut section of the line. Be sure not to allow too much pipe to be flared as this can cause the flare to split. Any split flare will not allow a proper seal and will leak. Cutting off the split flare and trying again is the only way to fix it.
6. After a good flare is on both ends of the new pipe and it is bent to the proper shape, 2 more flare nuts need to be attached to the cut sections of the old line attached to the car. Slide one flare nut over the end of the existing line, same orientation as before, and add a flare to the end. Repeat same process for the other end of the existing line.
7. Once all flare nuts and flares are in place, the new line section can be installed. Using an inverted flare fitting, thread in the flare nuts from the existing line and new line at the start and end of the new line section. Tighten the fittings. Some slight bending adjustments for proper fitment can be expected.
8. After the inverted flare fittings are installed and tight, refill the lines with fluid and check for any leaks. If leaks are present, try tightening the fittings even more. If leaks are still present, disassemble the fittings and inspect the flares for any signs of damage and inspect the inverted flare fitting for any debris.
9. Re-check fittings for any leaks. If all is good then you're all done.
