Jayd,
I agree 100% with Mike and Dave. My initial thought was that a localized hot spot is not going to affect your brakes - captive system, non-compressible fluid, etc. Like Mike says your fuel line may or may not cause you problems. The most potential problem is going to be those dog days of summer, sitting at a stoplight waiting for traffic, or even shutting down hot and restarting a few minutes later. If you're running EFI you likely have a return line, which is going to minimize the problems of a localized hot spot. If not you might look at shielding that area. If it were mine I would run it and see how it does before I start fixing something that may not be a problem. For me, going to the hassles of relocating lines would be several notches down the list. You may not need to do anything.
