Master Cylinder failed, causing all fluid to go into the booster, which resulted in no braking ability at all. fortunately I was in a parking lot when the occured, the vehicle was traveling at slow speed and was stopped by coming up against a curb. the low brake fluid warning came on at the time of total failure, this would have resulted in a serious accident had it occured on the roadway. the vehcle is being repaired at a local shop after it was towed there following this incident. An attempt was made to refill the master cylinder with brake fluid but it immediately empted with any attempt to use the brakes. there was no other visible sign of leak.

The contact owns a 2013 Ford F-150. The contact stated that while her son was driving at an unknown speed, the brakes became inoperable. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed that the brake master cylinder needed brake fluid added. The mechanic failed to locate a leak. The mechanic added dye to show a possible brake fluid leak. The vehicle was repaired but the failure recurred. The vehicle was taken back to the local dealer where the vehicle was diagnosed that the brake master cylinder fluid had leaked into the brake booster pump. The vehicle was not repaired. The vehicle was taken to an independent mechanic who replaced the brake booster and brake master cylinder. The contact stated that the failure was related to NHTSA Campaign Number: 16V345000 (Service Brakes, Hydraulic). The manufacturer was contacted and referred him to the NHTSA Hotline. The failure mileage was approximately 64,438.

I have had numerous brake issues on my 2013 Ford F-150 SuperCrew. One repair was done in the warranty period and 2-3 were not. This vehicle had less than 81,000 miles on it when all of this work was done. It was recently repaired and still isn-??t solved. I-??ve had two major accidents where my vehicle rear ended other vehicles because of its failure to immediately stop on braking. The dealership can-??t solve the problem or don-??t know how and I-??m afraid to continue to drive this unsafe vehicle.

I was backing into my parking spot at work and my dash dinged and the red brake system warning flashed on my dash, I couldn't push my brake pedal down, lost my brakes. This was very scary. I have lost them before, but not as bad as this time. They didn't come back this time. I am so glad I was in a parking lot and not around other cars.

Brakes are very hard to push the pedal, checked the vacuum pump, and have a good vacuum going to the master cylinder. Brake fluid level is good. Check brake system light comes on after the engine is started and running for about 30 seconds. All reports show that there is no current recalls on my truck.

2013 Ford F-150 SuperCrew FX4 w/ 3.5L Twin Turbo Ecoboost engine. 9/9/2022 8:30am: At start, some whirring/squeaking noise audible in cab. Became louder as brake pedal was pressed. Verified function of brakes before driving. 8:30am - 11:30am: Intermittent driving with stops and engine shut offs at various retail locations. Noise mentioned above still present. Brakes still functioning ~11:30am: Slowed to stop traveling east on Kingwood Dr just past Lake Houston Pkwy in Kingwood/Houston, Harris County, Texas. Prepared to turn left across west bound Kingwood Dr lanes to enter multi-retail plaza. After accelerating to ~10mph, pressed brakes and pedal went to the floor. The vehicle did not slow until pedal was at floor and grinding noise was heard from front brakes (noise similar to when ABS system is utilized). Nearly rear ended the car in front of me (within ~12in from bumper to bumper). Remained stopped until sufficient window of oncoming traffic appeared and plenty of safety space was present within retail plaza turn in. Accelerated gently (forced vehicle to remain in 1st gear) across Kingwood drive into plaza parking lot. Brakes remained in non-functioning condition. Vehicle only slowed when brake pedal was at the floor and grinding noise issued from front brakes. Slowly proceeded to parking spot and stopped (pedal to floor w/noise) and turned off the vehicle. Vehicle was then towed back to house. Significant safety issue as I nearly rear-ended another vehicle and had this happened less than 30 seconds earlier, I would have been trying to stop from a much higher rate of speed (~40mph).

Brake Fluid loss and loss of braking in traffic

- Kansas City , KS, USA

Complete failure of brakes on the freeway without warning. Local mechanic diagnosed the issue as "master cylinder leaking into the brake booster" which is the same exact issue that the 3.5 liter engine vehicles are having. The 3.5 liter engine vehicles have a recall, but not the 3.7 liter engine vehicles but it's the same issue.

Slowing down to make a left turn. Brakes failed very difficult to press brake pad and Power transmission system was not responding properly causing my truck brakes to fail, transmission was slipping and the rear tires to slide. End result was a Crash into a pole at a corner. My truck was totaled by the insurance company costing me over $9,000 to replace the truck after the insurance payment. Recall for Master Cylinder and Power train issued after my crash on 2/2/2018.

On August 8, 2022 I noticed a "low brake fluid" warning light on the dash of my Ford F150 truck and experienced greatly reduced brake function. There was no sign of brake fluid on the garage floor. I had AAA tow the truck to a repair shop where they diagnosed a leak from the master cylinder to the brake boost. The master cylinder reservoir was completely and at this point the brakes were completely non functional. I had the repair shop replace the master cylinder, brake boost and do a fuel system maintenance since some of the fluid was found in that system. Total cost to repair was $1583.83.

I was pulling a heavy load within the weight limit for my truck. I started down a steep grade 10mph below speed limit. I went to brake and I had none. The pedal was super hard. The check brake system light came on. I was freaking out because i was picking up speed fast. I had no choice but to shift to manual and down shift to try to slow down. It down shifted from 3rd to second but that was not enough to stop me. I was standing on the brakes. Luckily a "run away truck ramp" was coming up which i entered at about 30 mph. I am a very experienced driver and I was able to avoid a horrible accident but other people might not be so lucky. My brakes were fairly new and there was zero warning that they were about to fail completely. I looked online and saw hundreds of other drivers that had experienced this. Why is it not a recall? I could have died.

While driving down the road the low brake fluid light came on. I drove to a safe stopping area and found the brake fluid reservoir was completely empty. I checked for leaks at all areas under the hood and at brake calipers. No signs of any leaks nor any fluid on the ground. Filled reservoir and drove less than 1 mile and the low brake fluid light came on again. Stopped and checked the brake fluid reservoir and once again it was empty, still no signs of any leaks: based on research I have determined that it is a known problem with this make/model and year of the master cylinder seal going bad which causes the fluid to be sucked into the brake booster.

Heading home on fwy and brakes totally went out and low brake fluid light came on. Was able to pull onto side of fwy. All the brake fluid was gone and no sign of leakage. Was towed home. Filled brake reservoir up and as soon as I hit brakes again all the fluid disappeared. Upon inspection there was no sign of leak anywhere. I'm assuming the fluid is leaking into the brake booster since I cannot see any leaks anywhere.

I have a serious issue with my 2013 Ford F150 Limited. I almost had a horrible accident on I295 because of brake failure. Seems the brake fluid is leaking out and I didnt know this until I tried to brake and the pedal went all the way to the floor. Then the "brake fluid low" light came on. Upon Inspection after all the drama, got truck in a safe place, I checked and saw there was no fluid in reservoir. I filled it and pumped brakes a few times and pedal keeps going to floor then eventually it gained pressure..when I checked reservoir again, half of the new fluid was gone and truck was hard to stop again, So I had to tow it home. After taking to a shop I was told the fluid was leaking from master cylinder to the brake booster!! I then searched the internet, and discovered this is a common problem and Ford has a recall for this same exact issue my truck is having..Recall # 16V345000. Ford # 16S24. I then went to dealership to see if I can get fixed and was informed my VIN is not on the recall list and they wont fix. I called ford customer service and was told the same and also to contact NHTSA. So that is what i'm doing now.

lost all of the electrical power to my truck as I was going to drop it off at the dealership for a recall. On my way there my truck downshifted into first gear over revved the motor and caused it to shut the motor down and loss of the computer as well. I had it towed to my local shop. I called Ford to see what they want me to do next and said to have it towed there and I did.Ford cant get power to the truck because there motor is no good. ford also tells me that the oil is way over full. but I know it wasn't over full it holds 6 quarts of oil and I know that.so they state that the oil is over filled and blew the truck up. but the problem is the computer and in that event caused the motor to blow up and push gas and break fluid into the motor truck only has 80,000 miles on it. this I feel as a manufacturers default and frontier ford of Anacortes WA. And ford itself only honors there own techs so they are going by what they say. I have been dealing with this for almost 7 months with out a truck witch has cost me a job and among other issues and loses. feel as they didn't honor or care about the customer or even looking into the dealership that has my truck. when I asked to seek with a supervisor I was told they are no supervisor available and that they would call me back i have still never heard from them. How long must I be without a truck or a jib because they aren't doing there job correctly and making my life here impossible to get a head in such hard time as it is. Thank you [XXX].
