I've disc disconnected the brake line going to the rear brakes at the 5 way fitting and from the flex line just in front of the rear axle. I have removed it from all the retaining clips. I can slide it a good ways aft, but the loop that goes around the jacking point is preventing me from removing it from the frame. I am wondering just how this line is supposed to be removed without destroying it. I can see that I will add a coupling at a strategic point to allow for a 2 piece line in the future, but I was wondering how the heck they got it in there at the factory!
