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.
Breaks stopped working while I try to start my car, it went all the way to the floor. No warning , before it stopped, the warning came when it actually happen: "no break fluid". After a mechanic checked it, the brake master cylinder and break booster failed to work properly they needed to be replaced. The master cylinder is leaking brake fluid into the brake booster. If this would have happened to me driving on freeway or on road I wouldn't had any breaks to stop. My truck has been taken to Ford dealership they are fixing the problem.

I just had to have the vacuum booster pump for the brakes on my truck replaced again. The part number is: BL3Z-2A451D. It is the third time that I have had to replace it in the last four years: 6/26/20, 9/15/22, and 7/21/24. My mechanic, George’s Auto, in Crescent City, CA says that it is a faulty design issue, and has to replace several on other vehicles as well.
Ecoboost engine shut down on highway in rush hour traffic. Had my truck in the shop after 9526.00 in repairs and new engine it happened again this week. 1 year later. My truck was under 2 warranty extensions . And was in the Ford dealership at those times. I mentioned to service manager that it seems that possible could be the problem. Now I'm stuck with this mess . And it took 18 months for them to fix/ not fix it. Ford dealership
The antilock brake system locked up causing me not to be able to stop the vehicle .The shift gear froze up .When I put my foot on the brake pedal it was frozen, I could not control the pedal Also the shift level gear did not work presenting a safety hazard when I tried to put it in park. The Sudden Transmission Downshift which was a safety recall happened There were no warning lamps or lights prior to this incident. The accident caused me to total my vehicle My safety was at risk I injured my leg, I filed a police report I also filed a claim with the Ford company which they quickly denied stating that the recall on the parts had expired I only had liability insurance and my truck was a total loss. I hope I'm still in the time frame to put in a claim

While driving on the NYS Thruway my brake light came on and when I tried to engage my brakes it was difficult to push the pedal and the brakes were barely responsive. Now the brake pedal is difficult to push each time I start the vehicle and it barely stops when I begin moving. The rotors and pads are fine. My mechanic diagnosed the problem and it's a failed vacuum pump.
Brakes seem to go in and out from time to time . I keep getting the service brake system light on and will turn itself off after next key cycle . Dealer advised vacuum pump issues this should be a full blown recall

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.
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.
Vacuum pump is bad again. This was previously recalled. The part has failed now for the third time. Only once was I reimbursed due to recall, but it has since failed twice more. Currently at 98,000 miles.
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.
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.
I have a 2012 f150 platinum eco boost When starting vehicle in morning I would here a strange noise coming from the front driver side, now I leave out of driveway after starting and when I apply brakes the truck will not stop like there is no brake pressure and feels like anti locks are on, I have to sit for a couple minutes and then they work but they only appear to work manually I have to push brake pedal hard, I tried diagnosing like the forum says I put my foot on brake and start vehicle, the brake pedal stays hard and does not move, they say if this happens it is the brake vacuum pump. There is a recall 15N05 on my year vehicle but Ford says my vehicle isn’t covered it’s under the mileage and the correct year, I have to buy the pump myself, why isn’t Ford honoring the recall I just ordered part and if needed will upload the invoice later

THE ELECTRIC VACUUM PUMP FOR THE BRAKES IS MAKING A LOUD BUZZING NOISE. FORD SAYS THAT THIS IS A KNOWN ISSUE AND IT ISN'T A PROBLEM. AFTER DOING SOME RESEARCH I FOUND OUT THAT THIS IS JUST THE BEGINNING OF THE BRAKES GOING OUT. ALTHOUGH, THERE IS NOT A RECALL FOR THIS ISSUE. I'M NOT SURE HOW THERE CAN'T BE A RECALL IF THIS IS A KNOWN ISSUE IN ALL 2011 AND 2012 FORD F150S.
