Brake Line Placement for TT Disc Brakes

I'm in the process of accumulating all the required pieces for a spring 2017 disc brake mod to our 5er. I'll be using a BluDot steel line 'kit' from Eastern Marine rather then any of the kits seen on etrailer. First of all, IMHO, that so called universal flex line kit by Kodiak is a sloppy alternative. I'm also not sure that the flex line kit has DOT approval. A nicely run system is made up from steel lines, cut to correct length and properly clamped in a safe manner and area somewhere on the belly plus the axles of your trailer. This kit that I have includes 6 flex hoses. Two of these hoses (the longest ones) will be used to go from the 5ers chassis to the axles. The 4 shorter hoses will be used to go from the axle hard lines to the calipers. There is a note on the Eastern Marine offerings that say that the flex lines are used for floating calipers. Kodiak and I believe Titan as well use floating calipers. I' also going to add a flex line from the actuator, through the floor to meet with my hard lines.

You will need a couple tools. A 3/16" tubing bender - and this can be a low end tool, and a double flare tool. I can assure you that a low end flare tool here wont make you life good.

Any extra tubing you might need can be purchased at a real auto parts store, i.e. NAPA or CarQuest, not Pep Boys or Advance. I've also added 4 more flex hose brackets to my 'kit'

Then there is the 'fun' of straightening those coils of tubing. I made a 'die' from a piece of 2x4 with a slot cut in it with a table saw. It's just a few thousandths wider then the tubing and about 3/8" deep. I then pushed the tubing through an inch or so at a time. Decently straight with one pass and virtually perfect with a bit of hand tweaking.

Now - all I need is spring to spring forth
