Brake Grinding Noise problems of the 2012 Ford F-150

Truck made rumbling/grinding noise from rear-right bedside area, then while approaching a stop sign, an attempt to slow+stop the truck was made, but the pedal went straight to the floor and vehicle proceded through intersection, after pulling into safe spot, brakes started functioning correctly again. A few hours later braking completely failed. Truck is currently sitting until we can have a diagnosis (and repair) done. . .

Upon first starting the vehicle and putting it into reverse, the brake pedal becomes hard/stiff causing the vehicle to continue in reverse, even when increasing the effort in an attempt to stop the vehicle completely. At this time, a loud grinding noise can be heard as the vehicle fails to stop and continues to slide backwards down the driveway or parking lot. This happens in the morning when I leave for work, as well as when I leave the work parking lot. I live in a suburb surrounded by young kids and people out walking their dogs in the morning. It is extremely dangerous for me to back my vehicle out of my garage not knowing if there is traffic or pedestrians until I am completely outside the garage, at which time it is too late to stop the vehicle due to the malfunction where the truck continues to slide even after I push the brakes as hard as possible in an attempt to stop the truck from reversing. When investigating the problem, I discovered there has been a reported problem with 2011-2012 Ford F-150 pickup trucks with the issue as the 'brake vacuum pump failure'. When contacting several Ford dealers, my husband and I were informed that there has been a recall, but the recall was not specific to our VIN number as it was made in a different area; therefore, they will not pay for it. One Ford dealer associate was very rude about our situation as well. I should not have to be fearful every morning I leave for work that a small child may be crossing the sidewalk by my driveway when my vehicle's brakes malfunction, and neither should anyone else who is having similar problems but cannot receive the repairs due to having the incorrect VIN number, simply because our vehicle was not at the same location as the others.

2012 Ford F-150 ecoboost came off warranty in April, on July 2nd I started the truck, put it in gear (drive), and had no brakes. There was a grinding noise as if the abs was trying to engage. I had to practically stand on the brake pedal to stop the truck and put it back in park. Pumped the brakes a few times and tried it again same thing. I shut off the engine, turned it back on, and let it warm up a few minutes. Now it was ok. From then on when the truck started cold it has done this on a regular basis. Good thing I found this before I reached any speed, and while there was no cargo in the bed to add inertia. I did some research and reported to Ford that the brake vacuum assist pump was likely corroded, and that this was a known issue on 2011-2013 F-150 ecoboost models. They needed a Ford technician to make the diagnosis, which I was charged $100 for (to determine that I was right). They also reported a bad fuse for the pump. I am hoping nobody is trying to say that with a bad fuse these pumps will dissintergate in three weeks of summer weather? let's be honest- the bad pump took out the fuse, if the fuse was blown. They estimate a ~$900 repair. I opened a ticket with Ford motor company because this event exactly matches NHTSA preliminary investigation item pe15026. People with these trucks or anyone around them could get seriously hurt if the driver cannot react quickly or panics when this part fails, and it is a poorly designed part. Apparently this part was re-engineered for 2014 and later models. At the time of this writing I am hoping I can get some help from Ford. I am a long time customer and have had no prior issue with the dealership or their service department. This is a manufacturing quality issue, pure and simple. I just wanted to report in order to make sure that this case was included with the others related to pe15026.
