I remote started my truck and let it run to warm up. I got in and pushed the brake pedal and it went to the floor. I turned the ignition on and the information center said, "Brake fluid low". I turned the truck off, got out and looked under the truck for signs of brake fluid (there was none), opened the hood and my reservoir was empty. I took the master cylinder off and the brake booster was full of brake fluid. I had to replace both, the master cylinder and brake booster.

The master cylinder failed and caused brake fluid to be sucked into the vacuum brake booster. The result is total hydraulic failure of the brakes and a safety hazard. This is a known failure for the 2014 F150's with the 3.5L Ecoboost for which there was a recall. My truck with the 5.0L motor uses the same part.

RE: Safety Recall 16S24 Why is my 2014 F-150 not covered under Ford's safety recall (16S24) of a defective brake master cylinder? 16S24 covers defective master cylinders for the 3.5L V-6 Ecoboost engine, but not the 3.7L V-6 engine. Upon further research, it appears that both the aforementioned engines use the same master cylinder. See Motorcraft part no. BRMC203 (Brake Master Cylinder). According to Ford, the master cylinders' rear seal fails, thus leaking brake fluid into the attached brake power booster which causes pedal fatigue and possible loss of front brakes. My F-150 has a 3.7L V-6 engine, which is not covered under the recall. However, my F-150 is exhibiting the same master cylinder failure as is referenced in 16S24. My master cylinder has leaked into the power booster and the vacuum line attached the power booster has siphoned all brake fluid into the engine (approximately 60 ounces). The engine then expelled said brake fluid into the exhaust system causing white smoke to emit from the tail pipe.
