Brake Fluid Leak problems of the 2014 Ford F-150 - part 2

While driving on the interstate @ 75 miles per hour, the low brake fluid light came on. At that time I tried my brakes and the pedal went straight to the floor, started down shifting and using the parking brake to stop. Truck was towed to the Ford dealership, dealer informed me that the master cylinder had leaked all fluid from the reservoir into the break booster and into vacuum lines. Could be up to a month to get parts to fix. Dealers said it looks like this is a problem and that is why the parts are on back order. Why is there no recall on this?.

Brake light came on while driving at 65 mph. Immediately tested brakes and felt normal application. Three miles later approaching a four-way intersection, initiated second pedal application and brake pedal went to floor with no associated braking action. Used parking brake, gear down-shifting and road shoulder to avoid collision with other vehicles. Service inspection found master cylinder had leaked all fluid from reservoir into brake booster and into vacuum line. Replaced brake booster, master cylinder, vacuum check valve, and vacuum line.

While driving on the interstate a warning for low brake fluid appeared on the dash. Shortly after I lost pressure in the brake pedal when trying to brake for slower traffic. I was able to pump the brakes to slow down enough and was able to get to a near by gas station. Their was no brake fluid left in the reservoir and after adding more brake fluid the reservoir drained within 5 minutes with no visible leak. The vehicle was towed to the dealership. The brake master cylinder had failed and drained all the brake fluid into the vacuum booster. I was lucky that I enough room to pump my brakes to gain control, otherwise this could have resulted in a major accident. This part should not fail in this manner nor at 18000 mile of vehicle life. The mechanic at the dealership claimed he has seen this issues on other f150s too.
