I purchased the vehicle and a couple weeks after having it I got a brake warning and it said low brake fluid. I filled the brake fluid up and drove it a few more day and again low brake fluid appeared on the dash. I took the car to the dealer and they could not find a leak. And I drove the truck back home only to put more brake fluid in. I also told the dealer that my brakes don't feel safe when I push on them because they go all the way to the ground. I basically have been told they can't fix a problem they can't find.

On 5/17/2016 while backing out of a parking space, I applied the brakes to place the vehicle into drive and the brake pedal went to the floor. The truck did not stop immediately but I could hear the sound of what I assumed were the brake pads against the rotors and the truck slowly came to a stop. Immediately after the brakes went to the floor, the dash alarm indicated red and audible beeps telling me to check brake fluid. I left the vehicle in the parking spot and called for a ride home. We were approx 10 miles from home. The next day, Ford roadside assistance towed the vehicle to Ford of clermont. The service writer advised me that they would be replacing the master cylinder and the booster pump and should be repaired in a day or two. On 5/19/2016 the service writer calls me to let me know that they are replacing my lines as well and the Ford wants my brake system returned to them with fluid in the line so that they can inspect them for the failure. On 5/20/2016 I contacted Ford customer service and told them that although they are replacing the brake parts, Ford has not corrected the problem with the replacement parts. Ford did not offer to be proactive, they advised me that if the problem should happen again that I should contact them for assistance. I do not feel safe in this vehicle, I do not feel safe towing with this vehicle and I do not feel safe placing passengers in this vehicle.

While driving at 45 mph the [low brake fluid] light came on with an audible ding. Approximately 15 seconds later we stopped at a traffic light. Made a left upon green light traveled 2 tenths of a mile and readied to exit onto a ramp toward another road. When the brakes were applied the pedal went to the floor without any effect in stopping the vehicle. I immediately moved the vehicle's right side off the shoulder to slow down and pumped the brakes 4 more times which seemed to have a very minimal effect as I continued to completely let the vehicle come to a stop off the side of the road.once traffic cleared we turned the vehicle around and literally coasted 15mph into a food mart exxon 100 feet behind us and came to a stop as the wheels touched the curb. Then we called Ford roadside service for a tow to the dealership. After waiting 2 hours we proceeded to the dealership F-150 in tow. We were informed by the dealership that the master cylinder failed pushing all the brake fluid into the booster.

I got into my truck, started it - nothing unusual. Put the truck in reverse, it started back, I pressed the brake - the pedal went to the floor without stopping the vehicle. I believe it was probably idling a little higher than normal in warm-up mode. I had to engage the emergency brake to stop the vehicle and avoid hitting a fence. The low brake fluid warning came up afterwards, followed by a brake system red warning. I investigated, then had a mechanic neighbor assist me. There was no brake fluid leak evident - no apparent damaged brake lines or components. The neighbor indicated it was most likely an issue with the booster / master cylinder or the vacuum line. I put about 90 ounces of fluid in the reservoir during the trip to the dealership and it was 3/4 empty when I arrived. Still no external leak evident. The dealership treated the repair as a warranty item, and told me the fluid was saturating the booster which had failed. They replaced both the booster and the master cylinder.

While driving along a city street the brake fluid level low message came on while at the same time the brake light lit up on console. At this point had I had no brakes. Depressing brake pedal to the floor board only marginally slowed the vehicle. I was able to get it to a safe location without incidence. The dealer mechanic found the master cylinder had leaked and fluid drained into the brake booster. They replaced the master cylinder and booster. The vehicle only has approximately 29K miles.

While going down a toll road at 85 mph (the speed limit) a brake warning light came on. After pumping the breaks a couple of times it was obvious that I was losing fluid somewhere. Within 10 minutes the breaks barely responded to my pumping so I took the truck to the Ford dealer that was nearby. The master cylinder apparently failed with no warning or without any outside "issues". the truck has 69,000 miles so the warranty was no longer valid. Cost was almost $900 to replace.

Tonight on 5/13/2016 I had a complete brake failure and my low fluid brake light came on. I luckily was able to stop the truck without crashing but the gas me very concerned. I added a full quart of fluid and it was gone in 2 miles stein and I experienced another brake failure.

Low brake fluid light illuminated on the way to work. A few minuted later brake pedal started getting soft. Turned around and headed to dealership, brakes getting worse. Had to drive in low gear and double pump brakes. Got to an autoparts store after 4 miles. Master cylinder was empty. Bought fluid and refilled. Pedal was better, but not normal. Drove another six miles to dealership. Made it barely with no accident. Master cylinder mostly empty on arrival. Looked under the vehicle at both stops. No visible leakage. Also, when I took the top off the master cylinder to refill (engine running), could hear hissing. There seemed to be a vacuum on the master cylinder. Pretty sure that is not the way it supposed to be. I assume a seal failed somewhere and the vacuum assist sucked all the fluid out of the master cylinder.

I started to back out of my drive way and my brakes failed. The pedal went straight to the floor and a "low brake fluid" message came up on the gauge cluster. I had just parked the truck 1.5 hours prior and the brakes were fine. I looked in the master cylinder and there was no fluid. I didn't find any fluid on the driveway, don't know what happened. I almost hit the neighbors car backing out. I had to get my truck towed to the dealership. I should find out tomorrow what the problem is, but I find this very freighting that the brakes can just fail like that.

Service brakes - I have 29,000 miles and with out warning the low brake fluid light came on and loss of braking while I was sitting still. Went and got 2 bottles of fluid and filled drove 10 miles and all fluid was gone and so was brakes. Took truck to Ford and they replaced both the booster and master cylinder with the same oem replacement parts. This is not yet a recall but an investigation so with the same parts installed I am very nervous now to drive the truck until and remedy has been provided.

After driving to work I was existing the freeway, a low break fluid warning light can on. I proceeded about 4 blocks to the office I was working at, and parked the truck. When it was time to leave I started to back out of the parking stall and had a complete loss of brakes. I had to shift to park to stop the truck. With the truck in park I checked the brakes again and the pedal when all the way to the floor. I turned off the truck and called Ford road side service. I checked the brake fluid tank and it was completely empty, with no signs of any fluid leaking on the ground. After waiting 3 hours for a tow truck to arrive we finally got it out of the garage and delivered it to Ford of bellevue, in Washington state. The service adviser informed me that since I had about 37,500 miles on it it was not covered under the Ford 36,000 mile warranty. He said he would be in touch with me about what was wrong.

While moving at a slow speed I pressed the break pedal and the pedal went all the way to the floor without applying the breaks. I immediately released the break pedal and then pressed it again. On this attempt the breaks did engage.

I went to operate the vehicle today and brake pedal went all the way to the floor. A warning came on that brake fluid was low. I opened the hood and there was no fluid in the reservoir. I filled it up and started driving. Within two minutes the warning came on again. I again opened the hood and the reservoir was empty. There is no sign of a leak under the truck. Once again I filled it up and within a minute or two the low fluid message came on again and the pedal would go to the floor. I continued to drive it to the local Ford dealer very slowly, using the E-brake and gearing to stop as needed. Dealer could find no sign of a leak and thinks it may be the fluid bypassing the master brake cylinder and collecting in the brake booster. This is a very dangerous condition and I see I am not the only 2014 F-150 with defective brakes. This is a 5000 pound plus vehicle, one would expect it to have a very reliable braking system. Hopefully there will be a recall as a result of this investigation www.nbcdfw.com/news/local/us-investigates-420000-Ford-F-150S-for-brake-failure-371060011.html

Started vehicle after work, low brake fluid warning indicated. Pressed the pedal and it went straight to the floor. Vehicle has less than 17,000 miles on it and less than 2 years old. No brake pressure is a serious safety risk. Called Ford and they sent a tow truck. I have concerns that it could happen again even after the truck is repaired.

I had a brake failure identical to that of what has already been reported, within the last 6 months. While driving on highway, I went to apply brakes and pedal went all the way to floorboard & I had little to no brake control. Refilled reservoir but it was empty within 30 minutes. All fluid drained out of master cylinder and in to brake booster. Had to have master cylinder replaced, and have not had problem since.
