Brake Master Cylinder problems of the 2016 Ford Expedition

On June 30, 2021, while driving in a parking lot, "low brake fluid" warning lite came on then brake pedal went to floor. Brake fluid was added at scene but problem repeated it self. Car was towed to shop and diagnosed as master cylinder failure with brake fluid in booster. The parts were replaced and problem was solved. There is approx. 51000 miles on vehicle. Fortunately, this occurred at low speed in a church parking lot. I can't imagine what would have happened on the hiway at speed! defective parts are available for inspection.

Master cylinder failed completely while stopped. Brake pedal dropped to the floor with no back pressure. Brake fluid had drained into the brake booster. Same problem as the recalled f150! rear brakes were ruined presumably to front master cylinder failing silently.

Issue with braking system. Warning light turned on indicating low brake fluid, and within mile, the brake pedal hit the floor. Vehicle was in motion on a city street, and the brake failure was immediate. Was very fortunate I was on an uncrowded city street and was able to roll into a grocery store parking lot without incident. No leaking identified anywhere near the master cylinder or brakes.

Catastrophic brake failure during normal operation on a city street I was able to safely stop due to a low fluid light but by the time I was at a safe place to stop the brakes had almost completely failed. I had to be towed to dealer. Was told the master cylinder, brake booster, valve assembly, and vacuum brake sensor all needed to be replaced because the mc was leaking into the brake booster causing them to fail. This is the exact issue that the 2013-2014 f150s (very similar platform) had a recall for. Https://media. Ford.

Html service tech stated the mc had likely been leaking for some time to cause the failure. I had the vehicle in for routine maintenance at the dealer which included a full brake inspection which was given a clean bill of health less than one month prior to this failure.

Wife was driving home from work when the "low brake fluid" warning light came on going 45 mph. Less that one minute later when she went to stop and the brake pedal went to the floor and the vehicle would not slow down. Thankfully she was going up hill and able to get the vehicle to stop safely. Checked the brake master cylinder reservoir and there was no fluid in it. Checked the brake master cylinder for visible leaks and did not see any fluid.

Sudden and complete brake failure while driving the vehicle. Traveling with the vehicle on the highway when a warning message was displayed on the dash "low brake fluid". I touched the brake pedal and it depressed completely to the floor. I was able to stop the vehicle using engine braking and the emergency brake. Inspected the vehicle, no visible leaks at any of the wheels or in the engine bay. Brake fluid reservoir was empty. Had vehicle taken to closest Ford dealer. Was diagnosed with a damaged master cylinder that leaked into the brake booster and had to be completely replaced.
