Periodically lose brake power and it sounds/feels like the antilock brakes are kicking in. Typically happens immediately after starting and at low speeds (<5mph). Brake power is returned if i rev the engine in neutral or park. Nearly hit a person in the parking lot and did minor damage to snow fence today when backing up and could not stop in time.

At cold startup, the electric vacuum pump fails due to corrosion and the brakes do not work at all. The truck will not stop regardless of how much pressure is applied to the pedal during the first 2 minutes of startup time. This happens every time the vehicle is started after not running for more than 5 hours. I have nearly hit pets, kids, pedestrians, and mailboxes because of this. Parking attendants driving my…

When i started the car in the driveway and tried to move it 20 feet away from my garage, the brakes would not immediatly work and i came within 2 feet from hitting another car. I took the vehicle into the ford dealership and they informed me that i had a brake vacuum pump failure and i had to pay $900 to have it fixed. If there were a child walking in front of my vehicle, i would have not been able to stop.

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.…

When vehicle is started with a foot on the brake, and then put into gear, the brake pedal depresses completely and the abs system then kicks in to assist in stopping. The result was that there was a defect in the brake system's vacuum pump, which also blew the fuse for it. Under my extended warranty, the dealer replaced the vacuum pump, although not the fuse which caused a subsequent trip to the dealership as the…

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…

Electric vacuum pump fails and you loose your power brakes. Brake petal gets very hard with little or no braking power to stop. 2012 was the last year to use electric vacuum pump to supply power brakes and then was replaced in 2013 with a belt driven vacuum pump. This is a common failure in the f-150 from 2012 and prior year mdls.

I also have experienced the brake pedal going to the floor and not having any brakes when applied. The dealer replaced several parts to no avail. The first time it happened i was getting off the interstate highway and the brakes went all the way to the floor and i went straight through the stop sign at the end of the ramp. I believe the problem has been resolved but i am still very careful. I would love to find the…

After starting the truck the brake pedal was very hard like there was no power assist. It only happened periodically and i assumed my brakes were getting old. Brakes were replaced and the problem still existed at times. It is now happening more often. Just found out about the electric vacuum pump investigation and it sounds like exactly what is happening. Have not had it checked out professionally. I looked at it…

Occasionally, upon initial startup of vehicle, the power brakes would fail to engage, resulting in extreme force being necessary on brake pedal to slowly bring vehicle to a stop over several feet. This has resulted in near - hits of other vehicles in the driveway, basketball pole, camper, and house. Fortunately no impacts were recorded, but a major risk nonetheless. This phenomenon did not happen while driving, and…

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…
