You can buy completely new brake line kits, that use rubber brake hose instead of the steel brake lines. I have it on my tandem trailer and I loved the ease of that installation. They come as either single axle or tandem axle installations, complete with all the necessary fittings, cross over "t's", etc. And unlike metal brake lines, they do not rust out over time. Also, much easier to snake down the inside of a trailer box beam. (I used my electricians snake, and worked from the axle side to the front of the trailer... took all of about a minute to come out the front hole, then just taped the brake hose to the snake, pulled it back and was done with that part of it) The only thing you have to be careful of is to order the correct size kit for the length and width of the trailer, since the kits come in several different sizes and unlike a metal brake line that you can cut and double flare, you can't cut a rubber brake line, so measure carefully.
