2012 Ford F-150: soft or spongy brake pedal

Filed Jun 22, 2021 · Brakes · DE

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

Having very poor braking and a hard pedal feeling when starting truck after sitting in driveway for a few hours. Issue occurs each time I start the truck. I can't get the tires to lock up and the antilocks to kick in no matter how hard I hit the brakes. A couple of times while backing out of my driveway it felt like the power breaks weren't even working and I had to jump on the pedal with both feet to bring her to a stop before going out in the road or hitting a child.

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.

In february 2017 while backing out of a parking space on a down hill slop I was unable to stop the vehicle and into grass area almost hitting a tree in reverse. The power brakes were so hard I could not move the brake pedal. Once it came to rest I put the vehicle in drive and let off the brake pedal then reapplied the brake and they worked. I then took the vehicle to the dealer and they performed a recall fsa 15n05 on 2/27/2017 with 35,514 miles on the vehicle. Then on 2/16/2019 I was backing out of my garage and again could not stop the vehicle and went into grass hill of my yard.again my brake pedal was hard and no power brakes. When the vehicle came to a stop I let off the brake and reapplied and they started to work again. I took vehicle to the dealer that day for them to check it out. They notified me it again was the brake vacuum pump has has failed again and ford will not fix it since it was fixed once before under this recall. The dealer also told me they cannot fix it due to the pumps being back ordered for at least 30 days. So the first recall repair only lasted 19,108 miles and less than 2 years. Luckily no one was behind me behind me to get run over and no damage occurred. My feeling that this is clearly a safety issue and parts should last longer. It appears to be a problem since the part is now on back order and looks to be a poor design.

When backing out of driveway at approx. 5mph, the power brakes become spongy and can be pushed all the way to the floor. The vehicle fails to stop and the brakes must be pumped several times before they work. This only occurs at initial startup (first use of the brakes) that day. This happens almost daily during warm/hot weather months. The problem has existed since the vehicle was purchased and I have taken it to the dealership 2-3 times regarding this issue. However, they could not duplicate problem or determine the cause. It's been happening for the past 3-4 years and it's only a matter of time before I don't stop in time and backup into my neighbors car across the street. I have the 2012 ford f150 w/ eco boost six-cylinder engine and find similar complaints on the internet regarding this truck. A recall for similar brake problems was issued on 2013-2014 year models but not 2012. My truck is not used daily and has about 30,000 miles on it.
