The extra flexibility added to the brake lines allows cars to be assembled even though they are slightly different from one another. As for the coils they are there to serve as strain reliefs for the hard brake lines so that they dont crack due to the relative motion between the chassis and the body.

Why are brake lines coiled at the master cylinder. So one can only assume that the engineers had the right idea but the designers screwed it up. On one car the distance from the master cylinder to the anti lock brake system pump will be slightly different from that on another. Just find a piece of lead pipe the size of the coil you want clamp the pipe in a vise then wrap the brake line around the pipe. You can bend your lines in a straight manner to serve the same purpose if you prefer its just not usually as effective. A car is not always built with perfect accuracy. Looped probably would have been better terminology instead of coiled in this case just because were the conversation has gone down and through the brake system instead of just below the master cylinder.
Technician a says that these coils help prevent moisture from flowing from the master cylinder to the calipers. It should be coiled and it is very easy to do and get a perfect coil every time. The two looped lines that you see under the master in this photo. Also there is a clamp above the the coil between the coil and master. Why do brake lines curl off master cylinder. Two technicians are discussing why the brake lines are coiled near the master cylinder on many vehicles.
Act as though your trying to stretch the brake line around the pipe and wrap it as tight as you can. These explanations would make sense if all the lines from the master cylinder were coiled but theyre not. The coiled lines they are or were originally referring to are the looped brake lines off the master not the lines with the coils as in your photos.
