My brake system failed while driving. I had just left a parking lot when the braking system warning light came on. Coinciding with this the brake pedal pressure got much lighter with each press. Since I was within a mile of home I drove there and by the time I got home the pedal was going to the floor. I checked under the hood and there was no fluid in the brake reservoir. I did not see any leaks. I refilled the reservoir and let it sit overnight. The next day the fluid was gone again from the reservoir, no leaks around the vehicle. I had it towed to Lincoln dealership for repair and they said the reservoir leaked into the the brake booster. I had researched on NHTSA that this was a known problem for Ford/Lincoln and there was a recall, but my vehicle's VIN# was not included in the recall. The dealership replaced the master cylinder and the brake booster.

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.
