Do front brake line lengths have to be equal?

I'm assuming all the coils in the front brake lines under the master cylinder are to even out the length on each side. Is this correct? Is it necessary to have them the same length? I need to replace one of mine with more of a direct route, but wasn't sure if I could bypass all those coils or not.

I think the coils are mostly for flex between the body and the frame otherwise over time even the slight movement would tend to crack the line so you need flex hose or coiled line you should be fine as long as both tube have same diamater and i could be wrong

BnR has it right - the coils are for stress relief.

Okay, then why is there like 10 coils? I guess that makes sense, it just seems overkill.

maybe there was too long of a brake line and they needed to use up some extra length?

The coils are there to allow the body & frame to flex, as stated earlier. Coiling the lines makes them into springs, which allows movement with less fatigue of the hardline. It also provides a bit of extra fluid capacity in the lines, but that's really a moot point. At any rate, that is why they coiled them from the factory.

As for the length of the lines being equal - no it doesn't matter. once you have the lines bled they are full of fluid, which dosen't compress. Therefore, the fluid in the lines is essentially a solid connection... meaning that regardless of how long the line is, as long as they are full of pure fluid, they will apply pressure evenly.

the more coils you have the less each one moves,,the less it moves the less chance there is of it fatiguing and breaking
