Brake Line Mess

[mcgoo26]

So, I have been looking at this mess of tubing and trying to figure out what gives. As you can see in the picture, the tubes twist all over the place. There is one line that goes to a trailer brake which I plan to remove. Another line (part of it has spiral wrapping on about three inches of the line then looks like the other lines after) comes from the proportion valve and twist and bends and back to the cylinder. Another line has a significant bend at the fitting on the proportioning valve. Question is: does all of the bending serve any purpose and will re doing everything affect operation? Reason I ask is I want to clean everything up and route new lines. Wiring is a mess right now I know, that is in work. Thanks.
