Master Cylinder Brake lines

[WmBaldwin57]

I removed the master cylinder from my 65 Coronet, someone has added front disc brakes at some point. Look to be from a '73 Swinger or something similar. Anyway, the brake lines coming from the master cylinder did not have any loops in them, but I notice on a 73 Swinger that I have the lines coming out of the master cylinder are looped before they progress down to the proportioning valve. Is that necessary? Does it have something to do with keeping air out of the lines, possibly when brake fluid is low?

WmBaldwin57,

The loops in the lines act as vibration dampers to avoid cracking.

If "we" built trucks, cars etc with straight and short lines, eventually the constant flexing will cause fatigue in the lines and connections. This, over time will cause failure, at the junction or connector. By implementing coils and loops, it builds flexibility into the system. Preventing these stressors. Also, if loops are incorporated, and the line is damaged, one can "repair" the damage buy tightning the loop, providing "slack' for repair.
This was all determined 100years ago, Mechanical engineers from Detroit (bow your heads, a moment of silence, for yes this once Mighty city built the best cars/trucks on earth)!
Hope this helps

(Head bowed in reverence), Thanks for the help, especially the picture. Guess I'll be putting in loops since I don't have stretchy tubing
