1992 Mercury Cougar how to replace a brake line

1992 Mercury Cougar mileage: 95,000. The metal brake line from the right front wheel to the master cylinder has a small pinhole near the right fender wall down low. Replacing the whole line would be very difficult due to running behind the engine and having many curves and bends. What would be the best way to repair the line? I have been told I can use what was described as a "double flare kit". Cutting out the bad area and connecting a new section with fittings. In addition, can brass fitting be used or only steel fittings. I do not have ABS.
