This f150 is a 3. 5 ecoboost with electric brake assist vacuum booster. The vacuum booster started making a very loud noise when applying the brakes and it felt like the braking power was diminished. I took the truck to the dealer and they told me it was the vacuum electric assist pump that was bad. They did replace it and helped me with the price even though the truck was out of warranty by time. If this comes to be a recall, I would like Ford motor CO. To reimburse me my out of pocket expense.
