We received a low brake fluid light on the dash. I verified the low level was legit by inspecting the brake fluid reservoir, which was indeed empty. I filled the reservoir with DOT 4, I drove approximately 2 miles, and received the low level brake fluid alarm again. I drove approximately 17 miles until I could get more DOT 4, during this 17 miles I used the trailer brakes to stop as I had no Ford F-150 braking. I filled the reservoir with more DOT 4 and drove 2.5 hours home, with the low fluid level alarm in due my master cylinder and booster continuously leaking-?? the truck got turned in the Bill Brandt Ford where they found a leaking master cylinder and broken booster.

On 6-20-2021 the brakes failed on my 2014 Ford F150 3.5 V6 Ecoboost engine almost causing an accident. I found two recall notices but my VIN number was not listed. I took the vehicle to Ford in Livermore, CA and had it repaired. I then contacted Ford and I have a case number. I then went through all my maintenance history and found that there was actually a recall in 2017 with my VIN number. Apparently I did take the vehicle in and it was repaired. The recall was then deleted on my truck because it was repaired. Now in 2021 the same problem happened again. A master cylinder is a pretty simple part and should not fail this often. I will follow up on this with Ford.....
