Have had the vacuum pump replaced twice and it’s dead again causing brake failure, the timing chain stretch already cost me one engine and now a year later the chain has stretched again on the new motor not very happy about that and passenger air bag turns on and off randomly with no codes only a warning again for no reason.

Hello, I have a 2011 ford f150 eco boost. Just staring my brake pedal is very hard to push causing the vehicle to have no brakes. Took to dealer and said the vacuum pump is bad. Good new there a recall so they would fix for free. Mechanic called me back hour later stating the recall has expired so i have to pay for parts and labor. We are very confused why a safety recall that involves no brakes would expire?! This needs to get extended for safety reasons. I'm glad i didnt have my kids driving or they probably would have gotten into a accident! Please have ford look into this known problem.

Tried to apply the brakes and the brake pedal went to the floor without actuating the brakes. This happened suddenly and with no warning of any kind prior to the failure. I had to use the parking brake to bring the vehicle to a stop. The "BRAKE FLUID LOW" warning came on in the instrument cluster. The warning and the failure happened simultaneously, i.e. there was no indication of a problem until the braking system failed entirely. The vehicle had no braking action at all from the hydraulic brake system. Upon inspection the seals in the master cylinder appear to have failed, pulling all of the brake fluid into the brake vacuum-booster. It is my understanding that a problem identical to this one led to several accidents and a recall in the 2013-2015 F150. Clearly the issue is not limited to those model years as my truck is a 2011.

Brake failure - 2011 ford f-150, 6 speed transmission, brakes failed from a firm response to zero response (brake peddle went full in). Shop informed me master cylinder seal failed dumping brake fluid into the booster. Sensor also in failed condition. All three parts need replaced. Ford recall out for this condition on 2013-2016 f-150 6 speed trucks. This condition is the same for my 2011. Ford has told me that recall does not apply to my vehicle although similar. I was able to bring truck to a stop from 35 MPH on a city street. Truck stopped about 6 ft into intersection. No collision or wreck occurred. Truck in repair at this time. *tt

From a cold start, the service brakes did not work upon initial application. With extreme pedal pressure, truck eventually stopped rolling narrowly avoiding impact. Incident occurred in our driveway.

Had complete brake failure. Was able to get the truck stopped. Saw it was 2 pints low on fluid. Added fluid, drove towards my auto shop, had to stop to fill the brake fluid again (the light went on this time). Did this a few times. Just before I got to the stop, the truck blew out some smoke, chugged, and the motor seized up. Towed the truck to the shop, they found out the master cylinder leaked and the vacuum lines sucked the brake fluid out of the master cylinder and dumped it into the cylinders in the motor and this blew my motor. I hear there is a recall for this on 2014 f-150s but not on the 2011. Terrible design. A brake problem should not blow up my motor.

Complete brake failure. This is an absolute safety issue as I could not stop my truck until I put the vehicle in park nearly hitting another vehicle. The brakes will not stop the vehicle on cold start as the RPM's run slightly higher at idle. Took 2011 f150 to dealer for servicing of the brakes and dealer was able to replicate issue and stated vacuum assist pump is not working and will be covered under a recall. Brake vacuum pump was changed, dealer tested and called me and said truck was repaired. I pick the truck up from the dealer and back up, again no brakes, brake pedal is to the floor as I am still moving in reverse I put shifter into neutral and come to a stop. I then shift into drive to park the truck and again no brakes and drive over the curb protecting ford service department building before coming to a stop. Dealer performs maintenance and finds that the brake booster has an internal issue causing bleed off loss in pressure. I ask if this is a recall item and the dealer states that it is not. Waiting for repair to be completed and will cost $500 for parts and labor and was stated that this was a highly discounted rate.

While backing out of garage, after truck sat overnight, I had extremely hard brake pedal and almost no brakes, narrowly missing a parked car. After engine operates for a while, brakes return to normal operation. The problem occurs now when the truck sits overnight.

No assist brakes sporadically do not work, almost causing three accidents. Normally it is after the truck sits for a couple of days or when it's cold in the mornings. I put my foot on the brakes, start the truck, put it in reverse, and no brakes. I immediately press hard and the brakes grind coming to a slow stop. I've almost backed into a couple of cars. Another I backed out of driveways and couldn't come to a stop until I crossed the street hitting the opposite curb. This needs to get recalled before someone gets seriously hurt. The dealer won't do anything unless I pay $150 and leave the truck for several days so they can test brakes manually themselves. 1) huge inconvenience and 2) no certainty that it will happen for them as it happens periodically.

I was approaching a red light at an intersection almost in front of my work in town. I was driving approximately 25 MPH on boll weevil circle and applied brakes with plenty of room to stop. My brakes didn't seem to do anything so I pushed the pedal to the floor and I was barely slowing down. I believe I was slowing only because I wasn't accelerating. My anti lock brakes did not work. Weather conditions: light rain. I did not skid! I hit the driver's side of a blazer which was coming from the right perpendicular to me. Dps case 6687819 local case 2016-07-4597. I have hands free in my vehicle but no electronic devices were in use, there were no distractions. I was alone returning to work after lunch. After having my vehicle repaired I took it to the ford dealership and told them what happened. They ran a check and replaced the vacuum pump at no charge with a different type. I have had no issues since. Unfortunately, they did not cover my insurance deductible and the increase in my insurance.
