I was driving down the road and the check brakes light came on simultaneously with a low brake fluid warning. I went to push the brakes and the pedal went all the way to the floor. Luckily, I was driving slow enough in a low traffic area that I was able to bring the vehicle safely to a stop. There were no signs of a brake fluid leak and the vehicle received regular service (oil, fluids, tire rotation etc.) less than a month prior at a Ford dealership. We had the vehicle towed to the same Ford dealership where we paid over $900 for a new master cylinder and brake booster. The $900 bill hurt, but this could have been much worse. Through additional research, this appears to be a common problem among F-150S and Expedition (same parts) and somebody is going to get killed if the problem is not addressed.

While driving the low brake fluid light illuminated and check brake fluid warning alerted me, as I was looking for a place to pull over the brake pedal went to the floor board and no brakes were present. I had to apply the emergency brake to stop the vehicle. After stopping I opened the hood to check the brake fluid level and it was completely empty. No visible signs of a leak under vehicle or inside engine bay. It appears to be a total failure of the master cylinder and brake booster as noted in hundreds of other complaints on this Ford Lincoln brake system.
