I was watching a show on the Velocity network about truck modifications, and I saw the following closeup of the trucks master cylinder and booster.
What I don't know is why the designers put the loops in the brake lines coming out of the master cylinder? Everything on a car is there for a reason. I thought this might be for vibration, to give the lines some flex, but both ends of the line are secured to the same rigid body, so how much flex would you need?
Why are these loops in the brake lines coming from the master cylinder?
