While traveling at high way speed my brakes failed. We almost rear ended people and almost crashed into the divider. Thankfully the parking brake still worked.. We are very grateful that no one got injured. The truck is getting repaired at ford as I write this and it was diagnosed as master cylinder & brake booster failure.

Brake failure by model year
What owners say
It appears the master cylinder is leaking into the large black vacuum piece. Parked and went into shop in Safeway. Then came out and loaded kids, wife and groceries. Started truck, started to back out of spot, then tried to stop and no brakes, low brake fluid then comes up. I threw it into park and tried to think what is going on. Check the brake fluid and it is empty. Then go to gas station and add 2.5 pints. Start truck and wife pulls brakes and gets back to working, but notice the brake fluid is decreasing from resivior but seemed to stop. I topped it off and started to drive because brakes were working. After driving about 10 blockes, the low brake fluid alarm comes up again and I pull over and no brakes. Finally investigate and still no leaks anywhere. Finally look up online and find this is a common problem and you have recalled 2014 through 2017, but not 2012 or 2013, but seems to be a problem with this year as well.
On 22MAY2022 I started my vehicle and started pulling out of a parking space when I lost braking power. The failure resembled a similar issue I had in the past when the electronic vacuum pump failed and the brake pedal felt hard and required significant additional effort to bring the vehicle to a stop. The electronic vacuum pump and fuse has been replaced by the dealership previously. The unexpected brake failure caused me to roll farther than I wanted and hit the rock on my passenger side, rear door, causing minor body damage. Ford Customer Service said Customer Satisfaction Program 15N05 is a one time replacement and this vehicle is no longer eligible for the program since it has already been serviced. Additionally, they said any repair associated with this event is limited to 15N05 so body damage would not ne covered.
The contact owns a 2012 Ford F-150. The contact stated that the brakes failed to function as needed at the initial start-up of the vehicle. After shifting to neutral(N) and waiting for a while, the brakes would function as needed. The contact stated that the previous owner had stated that the vehicle was included in a previous recall for the brake module. The vehicle had not been taken to the dealer by the contact nor had the vehicle been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 96,000.
Brake Failure: The brake Vacuum Boost pump is failing which causes a loss of power assist brakes. This is a massive safety issue and can cause serious accidents. Oddly Fors no longer manufactures the Bracket to be able to replace the pump and there is no aftermarket alternative. My Dealer tells me their notes from ford say obtains from aftermarket but I have scoured the internet and nobody makes the bracket. IT's a terrible design and a huge safety issue that should be recalled completely . Ford watts to charge over $900 to fix it but cant even get the parts as described above. Transmission Lead Rail: Recently had the Transmission Lead rail fail whcih casued sudden downshiting at highway speeds and the shift indicator to not illuinate. THis again is a massive safetey issue that Ford issued sevral TSB on but never recalled. This almost got me killed on thehighway a few times. They charged me over $1500 to replace the LEAD rail when again this defcetive design and craftsmenship that is a massive safetey issue and should be fully recalled. Engine Stutter: My truck has almost always stuttered anytime you wne tover hal throtle, There are sveral TSB on this but FORD has not stepped up and taken care o fht eissue via recall. Apprnetly moisture build up in the inercooler and gets sucked into the intake due to poor design. Timing Chain Stretch: I now have Timing chain stretch, this also seems ot be quite common due to poor design. Rear Door Failure: I can no longer open my rear half door due to failure of internal plastic door components. You can research any o fhtese issues and find that htey are very common pronlems in F150 and other Ford vehicles due to their negligence in design and engineering and some are huge safetey issues that FORD has somehow been alloweed to ignore or issue insufficinet TSB instead of Recall.
Vehicle sat idle in garage for two months. Started vehicle and brake pedal went to floor and was very soft. A warning was displayed on the instrument panel showing low brake fluid. Noting that master cylinder reservoir was almost empty I purchased a pint of DOT 3 brake fluid which I added to reservoir to "MAx" fill line. Started vehicle, brakes pumped up to a normal pedal pressure, took for a short test drive slowly testing brakes. All seemed normal at that time. Approximately 3 hours later I started vehicle, again noting that the brake pedal went to the floor. Checked the reservoir and found it almost empty again. Looked under vehicle and found no indication of fluid in any of the four corners by the wheels nor under the master cylinder. It is my belief that the fluid is leaking into the brake booster a problem which was addressed in a Safety Recall 20S31 issued by Ford Motor Company for a series of vehicles which although does not include my vehicle I believe that this issue is directly related and could also cause serious injury and/or damage if not repaired. I will have this issue fixed at my expense, however, I would be interested to learn if any other 2012 vehicles have experienced this problem.
While coming to stop my brakes failed and went to the floor. On exit 32 eastbound I-90. Thank god there were no other cars in front of me. After looking online there is a recall for 2013 -2014 ford 150 that were manufactured at the same plant as my truck. In our research it takes the same master brake cylinder as the recalled trucks. Our truck only has 78,000 miles on it.
Very little to no brakes at all. Of course the same issue everyone else is having. Vacuum pump/ brake booster! Definitely a safety issue and how they haven't fixed this issue yet is beyond me. No actually I do know since I'm a ford employee myself, but I'll save that for a representative. Remember 'quality is job one!' [xxx] from louisville kentucky. Email: [xxx].

Hard brake pedal resulting in no or very little braking when engine is cold and vehicle is stationary, every day, every time I start the vehicle. Once the pump begins working or becomes unstuck, I do have brakes, however I am very concerned that this will result in brake failure and an accident with serious injury to me and my passengers. This vehicle has had a recall on certain models for this issue resulting from a bad vacuum pump. Ford customer service has said my vehicle is not involved in the recall. It obviously is, because it is the exact same problem involved in the recall.
Driving 75mph towing boat. Truck shifts into 1st gear. Redlined engine, many noises, slipping transmission, step on pedal to accelerate, it goes to 5k before shifting. Almost caused major highway disaster. Now my family is afraid to ride in vehicle. Also when first start up no brakes. Recalls where done for both , did not fix either.
Electric vacuum assist pump failures that resulting in the loss of brake power assist'making it far more difficult to get the vehicle to stop. This vehicle has 39,000 miles on it and it gives no warning . I am concerned with injury or a crash. The dealer states this is not a current recall. I have noticed there a several complaints and some crashes have occurred because of this issue.
The vehicle was in motion and as I was driving in a parking lot I went to apply the brakes but the pedal went to the floor and the low fluid indicator came on. I was able to use the parking brake to get the vehicle to stop. I opened the hood and found my reservoir was nearly empty but there were no signs of leakage around the reservoir. I got under the vehicle and could night see signs of leakage on brake line or any of the calipers.
