Brakes when starting
Hey folks, I have a 2012 Ford F150 Lariat Ecoboost and I have noticed that sometimes when I get in and start up, if I don't wait, the brake pedal will go to the floor, like the brakes are going to go out. This has only occurred on a cold start, but was wondering if this is normal during warm up or perhaps a recall or other issue?

Vacuum pump is used to build vacuum in the system for the brakes to work. (Boosted engines don't develop a lot of vacuum at idle.) It's a known issue so I'd pitch a bitch (politely) to your dealer about it. I bought a '12 used a little over a year ago and almost put the nose through my garage one morning.
I've read rumors that there is a newer design that's supposed to last longer but can't confirm that.

Thanks to you both. Much appreciated. I bought it used, from a Nissan Dealer. prolly not going to get much help from them on this, but it is good to know. I have found that after starting and a few pumps, it is good. It's getting colder so I have been using the remote start which helps. This is my first truck and for the life of me I can't figure out why it took me so long to get one, and even more a Ford. My 6'5" frame and gut fit perfectly and my three kids (15, 13, and 9) all fit in the Super Crew with plenty of room to grow. Already committed to getting another one.

I would check the brake fluid level. Then check the brakes all the way around.
Does it have any vibration while braking?
Sounds like you may have a wrapped rotor that is pushing the brake pads further apart so the brake pedal is traveling further, to put more fluid in the caliper.
