Ivo, in your position your best option may be a combination of a few ideas. I have made brake lines many times from premade straight tubes like this place has.. Click here
Straight pieces of pre-flared tubing of different lengths.
Of course you are going to have to know the diameter of the lines you need, that is VERY important.
But I have used these pre-flared tubes many times, get one close to the length you need and bend it to shape. There are adapters and junctions blocks in every form, thousands of different ones are available.
