Master brake cylinder failure. Brakes failed and had to run through a stop light. Same failure as Ford recall 16s24.
Loss of brake control due to master brake cylinder failure while vehicle in motion. Occurred immediately after brake system warning alert on dashboard. Brake pedal went to floorboard without any brake control. Checked brake fluid reservoir immediately after safety parking and it was empty. This event appears connected to the Ford f150 model year 13-14 with 3. 5l ecoboost engine master brake cylinder issue.
I went to operate the vehicle today and brake pedal went all the way to the floor. A warning came on that brake fluid was low. I opened the hood and there was no fluid in the reservoir. I filled it up and started driving. Within two minutes the warning came on again. I again opened the hood and the reservoir was empty. There is no sign of a leak under the truck. Once again I filled it up and within a minute or two the low fluid message came on again and the pedal would go to the floor. I continued to drive it to the local Ford dealer very slowly, using the e-brake and gearing to stop as needed. Dealer could find no sign of a leak and thinks it may be the fluid bypassing the master brake cylinder and collecting in the brake booster. This is a very dangerous condition and I see I am not the only 2014 F-150 with defective brakes. This is a 5000 pound plus vehicle, one would expect it to have a very reliable braking system. .
