After 71K miles, the brake master cylinder needs replaced due to brake fluid internal leaking to the brake boosters. Lost all control of braking power. $1100 repair to replace master cylinder and brake boosters. This happened on 7/6/2019 while driving home. The low brake fluid light came on while driving and noticed substantial loss in braking power and had to push brake pedal all the way down to slow the truck to a stop at stop sign.

While slowly pulling out of a drive way the driver applied the brakes but the pedal went to the floor. A mechanic's inspection determined the booster failed causing brake fluid to flow into the master cylinder. With no fluid in the lines there is no stopping ability.

I was parked at a retail store when the check brake fluid light cmae on. I check the fluid and it was almost empty. The brake pedal was going all the way to the floor. I purchase fluid and replaced it and drove home about two miles away. By the time I got home the light came on agin and the pedal was going to the floor with very little brakes. I called my mechanic (who works for Ford) and he said to check because he thought there might be a recall on the brakes. There is not one but there are a large number of complaints on the issue. It is so bad the master cylinder is on back order with no timeframe given on when it will come in. I also cannot get an after market part from someone else due to backorders. It is obvious there is a mass problem that Ford is ignoring a safety issue.

The contact owns a 2016 Ford F-150. While the vehicle was being serviced by antelope valley Ford (located at 1155 auto mall dr, lancaster, ca 93534, (888) 415-0959), the contact was informed that the brake booster, brake cylinder, and bushings needed to be replaced. The failure of the brake components rendered the brakes inoperable. In addition, the brake pedal extended to the floorboard. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 50,178.

3 miles into my trip with several starts and stops. Low break fluid warning light. Pulled over with working breaks but reservoir was almost empty. Loss of breaks after a couple more stops. Topped off break fluid reservoir. Ran motor 5 min before low fluid warning light, no sign of external leak. Leaking appears to be from master cylinder to vacuum buster. Pulled vacuum line from vacuum buster eliminated the loss of fluid. And was able to limp home with manual breaks.

I was driving on the North Texas tollway today. Get a low brake fluid warning light. When I tried to slow down the brakes went to floor. 0% braking. Fortunately, coasted tot a stop on the inside shoulder of a high speed tollway - dangerous. Eventually towed to park cities Ford (dallas, Texas). Had I taken the next exit I would have entered a busy multiple lane highway system from an elevated overpass. Very likely would have been a major accident with high likelihood of injury. This is a well maintained vehicle. Recent service. No wrecks. No brake fluid seen where the truck was parked prior to today's event. Absolutely, no warning.

I was driving to work and on my way about 7 miles into my drive, I received a notice on the instrument panel indicating my brake fluid was low, I click the ok button and continued driving, ummiediately upon coming to the next light to stop my brake pedal went to the floor as I pressed hard to stop, the truck did not stop and I ran the red light but making a turn and nearly hitting oncoming traffic. The truck camed to a rolling stop and I pressed the emergency brake and stopped on the side of the road. This truck I purchased last year in February of 2018 and has only 32,000 miles but Ford said the truck warranty had expired and the cost was $1235.41. I am fighting Ford and had opened a case but their investigation determined they are not at fault! I am here to see if NHTSA can have them recall their brakes.

The contact owns a 2016 Ford F-150. While driving approximately 30 mph, the brakes failed to stop the vehicle when the brake pedal was depressed. Also, 'low fluid' displayed and the brake pedal traveled to the floorboard. The vehicle was cautiously driven to an independent mechanic who diagnosed that the brake booster and master cylinder were faulty and needed to be replaced. The vehicle was repaired. The local dealer and manufacturer were not notified of the failure. The failure mileage was 68,767.

Came to a stop sign and everything worked, at the next stop sign it was as if someone flipped a switch (residential area with many intersections). My brake pedal would sink to the floor and could barely stop the truck. However if slamming the brakes the ABS would function and stop the truck as expected. Inspected brake system and fluid level was above minimum in the reservoir and found no external leaking of brake fluid (failure was internal to the master cylinder). Towed back home and isolated master cylinder and found it to be the issue. Replaced master cylinder and brakes function properly again. (when I removed the master the boosted still held vacuum and fluid was not leaking into booster. )

Left my home this morning and approached a stop sign and almost lost complete braking on my vehicle. Brake pedal was firm but almost no stopping ability. Brake fluid reservoir is full and brake pads and rotors are in good condition.

- Richmond, VA, USA

Complete brake failure. Parked truck and brakes worked normally. 15 minutes later started engine and brake pedal went to the floor. Brake fluid reservoir was empty. No leakage at wheel cylinders or master cylinder. 36,000 miles. No prior warning of low fluid until the failure happened. Towed to local Ford dealer.

After driving for on for about an hour I pulled off the highway and my brake peddle went very soft. Brake fluid low warning and my brake light came on. I go the truck stopped (slowly) and checked fluid - virtually empty. I nursed the truck to a service station filled fluid drove about 7 miles slowly to home and light came on again. Pulled in fluid was gone. Found that the fluid was leaking into the booster cylinder. Have to replace the master and booster cylinder. This appears to be an open investigation and it needs to be elevated before someone is seriously hurt. This could have been an accident easily.

My 2016 Ford F150 had total brake failure with out warning, this almost resulted in a major vehicle acident. The occured on a busy street with out warning the truck lost all braking and ability to stop.

- San Antonio, TX, USA

On 05/11/19 while driving I experienced nearly complete brake failure. I took the truck to my local mechanic who diagnosed the failure due to the master cylinder rupturing. Sequentially the leaking brake fluid drained into the brake booster which also had to be replaced. As this happened while I was driving it was quite miraculous no one was injured.

I went to drive into my garage and pushed the brake to stop and the peddle went to the floor. I pushed as hard as I could and it finally stopped just before I hit the back of the garage. It also happened then I was backing out of my garage. Same thing happened when I was on the road in traffic. I was going slow at the time. Sometimes the brake will be very stiff to push also. The peddle will barely depress. Like there is no power brakes. No warning lights come on in any of these situations. There is no warning at all. This needs to be fixed.

- Lindley, NY, USA

Brakes failed and it is related to the brake booster and master cylinder. Have to replace both at a cost of $1500. My understanding is Ford is aware of this issue but has not fixed the problem.
