Brake line

You could always buy one of the flexible brake lines, cut it to length and use a double flaring tool, double flare each ends and install the fittings on each end before flaring them. There are also them bendable brake lines in different lengths that already have the fittings on them. They are usually easy to bend. There is a brake line here bent to spec but as you see it's $110.00, it would be a lot cheaper to make your own.

If you have this system inspected I am sure you will also find that this is not the only line that is rusted. Brake line failure is extremely dangerous and can easily result in a serious collision. I have repaired many of these and it is a lot of work. The line is usually purchased in the roll and all the lines are custom bent which is not an easy job. I strongly suggest that you at least get a profession inspection to determine the integrity of the rest of the brake lines and repair them all at once.
