Disk brakes can warp. The heat from a longer downhill run can make them easier to deform and setting your bike down or bumping the with you leg can cause them to become slightly out of true. I had friend who was a little over dependent on riding his brakes and he warped two sets in the first couple weeks he had his bike. The solution to this was, instead instead of dropping $25 on new rotors, to bend the rotors back. Similar to truing a wheel. If it going to far one way give it a nudge in the other direction. Not a huge problem. And that really sounds like the solution because the OP said the brakes weren't rubbing the whole rotation only in certain spots which indicates a slightly out of true rotor.
