Brake Loud Noise problems of the 2012 Ford F-150

There is an issue with the electric brake vacuum pump. It males a loud noise when brakes are used and makes the brake pedal difficult to press down on and have a positive brake reaction. The first distance traveled after initial startup has very little brake activity due to the pump not creating brake pressure. It appears that it is a known issue by Ford as some trucks have been recalled based on their manufacture location, my truck was not made at the location needed to qualify for the recall and fix of the problem, however the same issue exists as those that do qualify.

2012 Ford f150. Consumer writes in regards to brake system recall. The consumer stated the brakes were repaired under recall, but the failure recurred. The brakes fail when reversing. When going forward the brakes have very little power and had a loud noise coming from the vacuum booster. The pedal was difficult to depress and had a major grinding issue.

Vacuum assist pump is failing at 33000 miles. This is the second pump that has failed. . Pump makes loud noise and vehicle loses braking ability brake pedal requires excessive force to stop vehicle and greatly extends stopping distance.

I have been hearing a loud noise behind my headlight on the drivers side for quite some time now. A few months back, my brakes didn't seem to work correctly and I rear ended someone. I am going through brake pads like crazy on my truck and my brakes still don't seem to work correctly. I was doing research and found out about the vacuum brake assist behind the driver side headlight. That's what's making that noise inder my hood & has got to be the problem for the loss of my brakes. If my brakes worked correctly I would have never rear ended car in front of me. I knew something was wrong at that point. & now I know the exact cause. But with everyone having this issue with the 2011-2012s, I think this is something that should be a recall. Ford should be the one paying for the wreck I got into since it's a common problem that's happening. Hopefully we could come to a conclusion before someone gets killed! I do have an accident report if you need more information from it.

During first startup of the day, the electric vacuum pump makes a terrible noise for approx. 10 seconds as it builds up assist vacuum pressure. The brake pedal becomes hard as a stone with no vacuum assist. This is due to a faulty design with the pump assy. It becomes corroded internally and externally, and the piston inside the cheap housing becomes corroded and the pump will eventually seize. This is definitely a dangerous issue. If the pump seizes, there is not enough vacuum assist coming from the engine to provide enough vacuum pressure to the brake boost system and the pedal becomes hard as a rock to press. This happens every day during first startup in the morning, and start up in the afternoon when the vehicle sits for a long period of time and vacuum pressure depletes.

Each morning, when I pull the truck out of the garage, the brakes sometimes do not work. Sometimes, it is very difficult to stop the truck. I heard it might be a vacuum issue, but it happens all the time, summer winter, etc. Truck was stationary to begin with. The brakes sometimes make a loud noise, as well. It's happened ever since I bought it, last year.
