Is anyone else experiencing poor braking and a hard pedal in their ecoboost? I am having very poor braking and a hard pedal feeling. I can't get the tires to lock up and the antilocks to kick in no matter how hard I hit the brakes at hwy speeds. A couple of times while backing out of my driveway it felt like the power breaks weren't even working and I had to jump on the pedal with both feet to bring her to a stop. I have had the truck at the dealer for four days now and they changed the vacuum pump but didn't seem to fix the issue. I needed the truck back since they did not give me a loaner and all I got from them is "when you get more time bring it back in because we don't even know if this is how the brakes are supposed to be or if there is an issue".
