Why coil brake lines?
Talking about an '87 E-350 with a 460 and fully optioned with dual batteries:
The two brake lines coming out of the master are coiled - making them maybe twice as long as they would otherwise be. There isn't much room in the engine compartment to say the least, and those coils seem to be always in the way!
Why does Ford coil them? What would be the result of replacing them with straight[er] lines?

The coils act as shock absorbers for the brake lines. They lengthen and shorten like a coil spring in a suspension. This keeps the fittings tight and lined up in the master cylinder, and keeps the lines from braking/cracking since they are seperate from the body, which is on rubber to isolate it.

To prevent movement and vibration from causing metal fatique to outright breaking. The body and frame on any light truck moves up, down, and sideways a lot.

A crack from extension, compression, shear, or vibration. This is why you see so many "lifted" trucks lose their brakes and go down a steep hill out of control and crash into something when they lose their brakes. Lousy brake line routing and forming.
