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 the truck has 69,000 miles so the warranty was no longer valid.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.

The contact owns a 2014 Ford F-150. While driving 20 mph, the brakes failed and brake fluid leaked into the master cylinder. The brake fluid light illuminated. The issue recurred. The manufacturer was not made aware of the issue. The VIN was invalid. The failure mileage was 45,000.

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.

After letting the vehicle sit for about on hour I checked the brake fluid level again and it was empty but no fluid was on the driveway under the vehicle. I had the vehicle towed to the dealer and I have been informed that the brake master cylinder and the booster tank must be replaced.

- Houston, TX, USA

Truck was parked on a hill and when I returned I got message low brake fluid and had no brakes. I added brake fluid and within 2 minutes it all leaked out, but nothing on the ground. Had truck towed and the Ford service department said all the brake fluid had leaked from the master cylinder to the brake booster. Both were replaced by local Ford dealership under warranty. Truck had 10,000 miles at the time. Seems like this is the same issue many others have had. Very dangerous. Hopefully a recall will be done before somebody dies because of it.

I got out and checked the brake fluid reservoir level and it was completely empty but, there was no leaks anywhere, the truck had to be towed to get fixed. I discussed it with joe and upon exploring this further joe came across the attached article and it turns out this sudden total loss of breaks has happened to several other F150 truck and are being investigated

- Houston, TX, USA

Ford F150 supercab 4X4 5.0 automatic. Purchased vehicle new in February 2015. Shortly after purchase, I noticed the truck would begin to creep forward while stopped in traffic with the brake applied. This would require more effort to be applied to the brake pedal until the pedal would eventually go all the way to the floor. I took the truck in to the dealer at around 500 miles to have the brakes checked but was told that this condition was normal for power assist brakes. I have owned many vehicles with power assist brakes and this condition is not normal. The truck now has 11000 miles and the condition persists. Based on complaints from other F150 owners it appears that these trucks are equipped with defective master cylinders which are bypassing. So far I have not encountered a total brake failure but the braking problem with my truck could be a precursor to complete failure. I know that the brake problem has mainly been identified on trucks with the 3.5 engine but Ford has acknowledged that it could affect trucks with other engines such as mine because it has the same braking system. While I had my truck at the dealer I was also told by the service manager that they checked the brakes on a new 2014 F150 on the lot and the brakes did the same thing as mine, therefore it was a"normal" condition. This appears to be a widespread problem and it is only a matter of time before there will be more accidents caused by these faulty master cylinders.
