I never noticed any issues with the brakes or anything else ...
When I brought the truck back to the dealer, my sales guy and I tested 3 EBs on the lot and they all made that buzzing sound from behind the headlight.
Did all of the ones on the lot sound they were about to self-destruct? My 2012 EB with 7000km on it (5 months old) started making this noise yesterday. I had never heard it before. It was quite loud, and I was able to record the noise on my phone for the service people at Ford. It happened 4-5 times at the beginning of my ride to work, for about 10-20 seconds per time.
They tell me it's nothing to worry about and that it's just the normal sound a mechanical vacuum pump makes, but I wonder how I went 7000km on it without ever hearing it before. No weather changes or anything to speak of, I had the radio at the same volume as always, yet I heard it over the radio and moreover, I could feel it in the form of vibrations through my foot on the brake pedal.
To me, it sounds like there would be a low noise as the pump works, but for the sound to be that extreme all of a sudden sounds to me like something's wrong with pump itself.
