Hy dogdaddy, it is difficult to tell for sure from the pictures, but it appears to me that your rear brake line tubing is mounted to a bracket/tab which is attached to the rear axle, your flex brake line continues from there. If that is actually the case, it will be a short time of driving before the metal brake fractures and then no or partial brakes. The rear brake flex line must run from the frame of the truck to a distribution block on the rear axle, this allows for the up and down movement of the rear axle without stressing the solid tubing.
