The brakes became hard out of nowhere and wouldnt stop while I was driving, at night! I don't know if it's a vacuum issue or what it is. Very dangerous!

Brake fluid leaked from the brake mastercylinder into the brake power booster. Once the brake fluid level in the mastercylinder reached a high enough level, brake fluid was sucked through the vacuum lines into the intake and into the engine, where presumably it filled up the cylinders. This occurred both while in motion and stationary, I suspect it only occurred while the engine was running and a vacuum was on the vacuum lines.

Brake fluid filled the booster and ruined master cylinder.

The brakes went out on my 2013 F-150, the master cylinder leaked brake fluid into the brake booster. 'I was driving and went to stop at a stop sign and the brake pedal went straight to the floor I was lucky there wasn't a vehicle in front of me or I would have hit it. 'I pulled into gas station and got dot 4 brake fluid and filled up the reservoir, the indicator light showed 98% full. 'I drove couple blocks home and went to stop and the brake pedal went straight to the floor again (I was lucky I did not go thru the garage).

2013 Ford F-150 recalled by Ford in 2016 under recall 16V345000. Vehicle had the defective hitachi master cylinder replaced in may of 2017 by jenkins Ford in fort meade Florida at no charge. On July 30th 2020 while traveling on an interstate depressed brake pedal, travelled to the floor with minimal braking and brake fluid low level light came on with warning chime. Remained in control to stop vehicle with no accident. Vehicle towed to bartow Ford, diagnosed as faulty master cylinder seal allowing complete bypass of brake fluid into the vacuum booster. Ford refused to pay for this repair $1282 claiming they had fixed this problem in 2017. Upon investigation confirmed that the defective hitachi master cylinder was replaced with another identical defective hitachi master cylinder. It makes no sense to try to correct a defect with the identical defective part when the braking of a 6000 pound vehicle is at stake! I just saw another recall just out for 2015 thru 2018 F150 with the same poorly designed single seal master cylinder. How many other complaints have there been for the replacement master cylinder also failing?

The master cylinder is dumping the fluid from the primary reservoir into the brake booster, resulting in the loss of brakes. My vehicle was not covered by the previous recall (16S24), but is experiencing the same issue. My vehicle is a F150 platinum with the 3.5L eco boost engine. The vehicle has approximately 87,000 miles. The brake loss occurred while the vehicle was sitting in a park.

I have a 2013 F150 that the brakes went out on. Mechanic diagnosing it says master cylinder is leaking into the brake booster. There is a safety recall for 2013-2014 F150's but mine is not included on this recall...why? I was driving when I went to stop at a stop sign and the brake pedal went straight to the floor. I was lucky there wasn't a vehicle in front of me or I would have hit them. I was in a neighborhood.

Drove truck to work no issues. Went to leave for the day, pressed the brakes to shift into reverse and brake pedal went to the floor followed by a brake fluid low message. Checked fluid and it was below min line. Checked for leaks under and at each wheel. No fluid found. Contacted Ford to check for recall and they stated my truck was not part of their brake master cylinder recall.

Driving in a neighborhood down a steep hill and brakes failed and pedal went all the way to the floor. Almost crashed into a house. Had to slam on emergency brake and slam gears into a downshift mode. Came to a stop at the yard. The shop said the lines broke at the caliper in the rubber lines and fluid was all over the under carriage.

While travelling on the highway, low brake fluid warning came on, and when exiting the highway the brake pedal went to the floor and I had very little braking efficacy. Fortunately, the highway exit was slightly uphill and the traffic light was green with vehicles starting to move and I was able to coast through the right turn at the green light. This occurred on the elgin-O'hare tollway (I-390) in hanover park, Illinois where the elgin-O'hare (I-390) westbound meets lake street. My 6 year old son was travelling with me, and we are very fortunate to have had the situation work out in our favor. Had we been travelling home instead of away from home, the exit ramp we would have used was downhill and typically ends at a very busy intersection.

Brakes when in reverse or forward at idle do not work properly and take extreme pressure to operate if they operate. This causes a loss of braking and being unable to stop vehicle. This happens anywhere I am at idle. Parking lots, parking spaces, or road at stop signs. The brake pedal does not want to depress regardless of how much pressure I apply. It is mainly intermittent but will happen nearly each time if you depress the brake pedal multiple time in short succession.

I had a brake failure on 01/06/2020. I had it towed to a garage and they replaced the brake booster. In the shortly after it happened again. Both times it only occurred at low speeds on city streets. I contacted a dealership after seeing there was a recall for the same issue on my year of truck. They advised my truck wasn't covered. I'm afraid to drive it.

- Tipp City, OH, USA

Hauling a full 2 horse trailer. Approaching a red light when I hit my brakes they went all the way to the floor. I had the truck towed to my repair shop. They discovered a slice in the brake line. In all of their years of experience they have never seen this. See attached photo.

- Lafayette, CO, USA

Brakes go all the way down to the floor. Appears to be the same issue as some of the other 2013 models were recalled for, but for some reason, Ford didn't include this model. This model should be included too.

- Tucker, GA, USA

I was driving on the interstate and the brake fluid level indicator light came on. I was able to stop safely and check the fluid. The master brake cylinder was close to empty. I had just had my vehicle serviced so this was odd. Upon attempting to drive again I found that I had no brake power.

On June 3, 2020, my son and I were in my 2013 Ford F-150 driving West on I-94. My son was driving. An alarm sounded then a message appeared on the dashboard about an issue with the brakes. I don't recall the wording. We had driven about 25 miles from home with approximately 35 miles to our destination. We continued on and I got out and my son remained in the truck for about an hour. He then got out and looked under the truck and there was no liquid under the truck. I returned to the truck and we headed home on I-696 then I-94 with no issues. The brake message on the dashboard was lit. When we exited I-94 at the marysville, Michigan exit we had a complete and total brake failure. No brakes! my son stepped on the emergency brake forcefully and was able to slow the truck down enough to make the turn off the exit ramp and on to gratiot road. He ran through the stop sigh there in making the right turn on to gratiot road but thankfully no traffic was right there at the same time. We drove the additional half mile or so to our house and parked the truck. We checked the brake fluid level and it was empty. We then drove my son's car to auto zone and bought a quart of brake fluid and poured it in to the F-150. After a couple hours we checked the brake fluid level and it was empty. There was not a drop of fluid on the cement driveway under the truck! we called marysville tire and auto, Inc. And drove the truck the less than half mile to their location. They put in a new master cylinder at a cost of $519.04. I called Ford motor owner relations and made a report (case #26860820) on June 19, 2020. Research shows me that other F-150S have been recalled for replacement of a master cylinder and I want you folks to know of my experience. There has never been any fluid leaks under my truck since I purchased it in 2014. Thank you.

While driving interstate, 65 mph, towing travel trailer (6500 lbs). Clear weather day, 72 degrees. Brake light warning light illuminated. When trying to exit interstate to investigate issue, experienced complete brake failure, both front and rear. Fortunately, I was able to use trailer electronic brakes to stop my vehicle. Upon inspection, I found no loss of brake fluid. No visible explanation for total brake failure.
