I was driving and the low brake fluid warning light came on and started alarming and then went off. The parking brake light remained on and I checked my brakes and they were okay. I made it a few miles on a 4 lane major highway and started to put my brakes on to slow down and get into a turn lane to turn left and my brake peddle went to the floor. I realized I wasn't going to be able to make the turn so I made sure it was going to be safe to remain straight and I started down shifting to slow down and then started slowly applying the emergency brake as I was exiting off the shoulder of the road. I was able to safely stop. I checked my brake fluid reservoir and it was empty. I had no leaks under my vehicle. I got some help from my dad and ended up driving it to the local ford dealership. I burned through 1 gallon of brake fluid getting it there. I found out that the brake fluid was going from the reservoir to the brake booster and then vacuum to the engine and being burned up that way.

Page 4 of 12: complaints 71 to 100 of 317, newest first, as owners wrote them.
Brake failure. Brake pedal went completely to the floor and vehicle did not stop until it hit a tree. I pressed the brake, started the car. The brake pedal did not feel abnormal. With my foot still on the pedal, I put the vehicle in reverse. The pedal immediately went soft and completely to the floor. Since I was in my driveway only planning to move the vehicle back about 3 feet, I did not close the door. When the vehicle did not stop, its door caught a tree and bent backwards into the front fender. The vehicle stopped because the door caught the tree. The only warning displayed on dashboard was that the door was open and the car was not in park. After incident I turned on power to vehicle without starting to record the mileage on the vehicle for my insurance company and that is when the low brake fluid warning came on.
Master cylinder and brake booster failure - 2015 ford f150 s-crew 56k miles. . Without any warning, the brake pedal went to the floor and fluid level warning appeared. Added brake fluid and took the vehicle to the dealership. After a diagnostic it was determined that the master cylinder and brake booster needed replacement. Fortunately when this occurred I had just started the vehicle to return home from work. There was a recall for this specific issue on the 2013 and 2014 model, but not for the 2015 which seems to be following suit.
Driving on the highway saturday may 30 and without warning the brake fluid low warning light started flashing. The brakes were barely usable and the pedal had no pressure and stopped just off the floor. I could use the brakes but very slow to stop the vehicle. I could use the pedal for the emergency brakes but just barely. I was driving on an interstate at 65mph , towing a 23' boat, I was not using the brakes at the time of failure, there was no warning prior to the failure. I had the truck serviced on may 13th and had casually looked the night before the trip and noted no problems. I stopped bought fluid and filled the fluid reservoir and 15 miles later the same warning light came on. Stopped and looked for leaks under vehicle and at each wheel and nothing evident. Had someone meet me and tow the boat for me as I limped the vehicle to dealer.
On friday may 29 2020 I had to stop for an emergency vehicle and my truck lost all brakes it went right to the floor under normal use they appear to work at about 75% my vehicle was in motion on a city street going straight.
Complete brake failure. Only warning was indicated that the brake fluid was low. Ford dealer stated that the brake fluid from the master cylinder leaked into the brake booster and contaminated the brake vacuum sensor and manifold tube, .replaced all items.
Break master cylinder and break booster went out. No notice when driving.
While driving my local roads at about 45 MPH I received a warning on the dash for "low brake fluid" followed by a solid lit brake light on the dash. I made it home with noticeably spongy brake pedaling. I opened the hood to see the brake fluid reservoir was empty down to the sensor connected on the side. I filled it with the appropriate brake fluid to just below the max line. I pumped the brake pedal until it felt normal again. It has not moved since yesterday (april 8 2020). Today (april 9 2020), I go to take a short trip for coffee. When I start the truck and touch the brake pedal it went immediately to the floor with no resistance. Without attempting to move the truck, I immediately popped the hood and saw that the reservoir was completely empty this time. Overnight it appears that the entirety of the brake res. Was drained and it had not been driven since being topped off. No leaking under the truck nor on the driveway has been noticed. It is being towed to ford dealer service department today for this brake issue. I'm lucky I was not going at higher speeds when this occurred seemingly so abruptly. I hope it's fixed and recalled soon. My ford dealer informs me that it's not currently covered under a recall.
While driving on the interstate, my low brake fluid warning come on, I pulled over and had to cruise to a stop because the brake pedal was hardly responding. After getting 2 12 oz. Bottles of brake fluid brought to me, I filled up and pumped them up, seemed ok so I started again, light came on again after about 5 miles. Brake fluid reservoir was completely empty. Did this 2 more times, dumping more than a gallon of brake fluid into the reservoir. Mechanic has found no leaks in the lines.
I was leaving the house when the dash display told me I was low on brake fluid.found it a bit odd so I added fluid. Shortly down the road the message came on as I was fixing to come to a stop and the pedal went to the floor. I nearly hit a minivan. I limped it back home at a very slow roll and parked it. I have a call in with ford seeing if they plan on doing anything since this is a safety issue, doesnt look like I am going to get anywhere with them. Appears I am gonna have to shell out the cash and get it fixed on my own dime.
I stopped while pulling a trailer, fueled my vehicle, hopped back in and the trailer brakes were on constantly. I disconnected 7 way plug and trailer brakes released. I tested trailer braking output at the 7 pin plug and the brake output was stuck on. I turned the gain down to zero and it was still staying on. I checked the trailer for a short and all check showed trailer wiring as ok. I found on an f150 forum many complaints of the same thing happening to 2015 and 2016 f150's and dealers replacing the trailer brakes module and the tow module.

While trying to pass a dump truck on the interstate with adaptive cruise on, vehicle slammed on the brakes, and causing the vehicle behind me to slam on theirs to avoid hitting me.. I noticed that there had been a recall for this before in 2015, but I never received any notice of this.. It is a very serious road hazard!!
Brake fluid is leaking. I was driving and all of a sudden my brakes went all the way to the floor and I nearly lost control of the vehicle. I also got a notice of low brake fluid, so I put some in and a few days later it was low again. I noticed that it is leaking out onto other parts under my hood.
As I was driving on the highway, I got a warning on my dash saying the brake fluid level was low, accompanied by the brake light illuminating on the dash. As I went to pull over to a safe location, the brake pedal went all the way to the floor when I pressed the pedal. At this point I had no power from my brakes, having to stop by downshifting and using the emergency brake. Upon inspection there was a very small amount of brake fluid in the reservoir and no visible signs of a leak or broken brake lines. I purchased brake fluid and refilled the reservoir. Within 2 miles the warning illuminate again with the brake pedal going to the floor. I had to have my truck towed to the dealership for repairs after this incident.

I was driving my 2015 f150, towing a trailer of around 7000 lbs. All of the sudden my truck said 'low brake fluid' and the pedal went straight to the floor. This happened on a highway. This turned out to be the same problem that ford recalled in the 13-14 models. The master cylinder leaks into the brake booster, leaving no trace of leaking brake fluid, and therefore you will not know until it is too late.

The factory/ dealer installed tow brake controller does not apply enough brake power to stop trailer. When towing my 5th wheel(10000lbs)it works fine when I manually apply the override button but when I apply the brake pedal the trailer brakes don't get the command to engage with enough power to stop trailer, my truck is doing almost all of the braking. I have read online where many ford f 150 owners are having similar issues. Ford says there is nothing wrong. I have been towing using the manual override switch or learning to slam on the brakes to stop. The trailer brakes do work almost when I slam on the brake pedal. I am sure that this shouldn't be happening because it's not safe.
On 09/22/2019 while driving, on a local city street, where the speed limits vary from 30-45 MPH, my brakes became completely ineffective while driving in a 45 MPH zone. My vehicle is a 2015 ford f-150 with 63,000 miles. I inspected the brake fluid reservoir, and it was completely empty with no sign of leakage anywhere. I did a quick search on this issue and learned that ford had issued a recall for the same issues on the 2013-2014 models, but not 2015 and up, which are now experiencing the same symptoms. The vehicle is currently at a local ford dealership where I am finding it difficult to get a resolution. The dealership has confirmed at this point that it is the brake master cylinder that has leaked fluid into the brake booster, which caused the loss of brakes, and is the exact same problem as the recall for the previous year models. The dealership is supposed to provide me with an estimate of the repairs, but have yet to do so after a week of being at the dealership.
