I have a question about the metal coils that go around the stock brake lines. Are these a must have, or just to protect the lines in critical areas?

I read somewhere a while back it they had something to do with harmonics. Don't know if that's factual or not.Shielding. Question:whats that spring wrapped around some brake drums for?
Harmonics. There is a section of freeway near by that causes your tires to sing. Fairly loud. For about a half mile. Funny thing is I never hear the cars around me singing,just the car I'am in. Wonder if the guy who cut the grooves got fired? LOL.I read somewhere a while back it they had something to do with harmonics. Don't know if that's factual or not.
