Brake pedal pulses when wiper activates.

[newmarket23]

Hey guys and girls. I just got my 2012 f150 last week and we just got a crap load of rain. Now I didn't know where to post this so I hope this is the right spot. Whenever the wiper activates, I feel a strong pulse in the brake pedal if I am stopped at an intersection. I don't know but is this normal?

Yes it's normal my wife has a 2012 fx4 ecoboost and it does that I looked into it and found nothing asked the service department at ford and they said they don't know either
