In September 2019 my brakes failed on me while driving my truck. The red brake light on the dash came on while I was driving to work and the dealership diagnosed the issue as "master cylinder leaking into the brake booster" on my Ford paperwork. They replaced the brake booster and master cylinder for $858. Then on November 2020 they performed a recall to install a new master cylinder under the open recall and after much arguing they refunded my prior $858 charge. On August 8, 2021 in less than 9 months and just under 9000 miles later the newly installed master cylinder failed while I was driving down a mountain road. I had my family of 4 in the truck and we lost all brakes. This time there were NO WARNING LIGHTS, we just lost the ability to stop the truck while going down the mountain. The vehicle was towed to the dealership but the brake fluid reservoir was 100% empty and the dealership will diagnose the issue in the next 24-48 hours. This is EXTREMELY DANGEROUS and I do NOT feel comfortable driving the truck.
as i was driving home. i noticed that my brake pressure was getting low. when i came to a complete stop my foot went to the floor of the truck. LUCKILY i was able to pull over. when i checked the brake master cylinder reservoir the brake fluid was COMPLETLY gone. i was reading that Ford issued a Recall on on the 2014-17 Ford F-150 vehicles built at Kansas City Assembly Plant, Sept. 1, 2014 to Aug. 1, 2016 which mine was. i contacted Ford Motor Company and they stated that the recall was on a the 3.4 eco boost engine and and not the 2.7 which mine has. How does Engine Displacement make a difference on a defective Hydraulically master cylinder.
The contact owns a 2015 Ford F-150. While driving 35 mph, the low brake fluid warning indicator illuminated and the brakes became inoperable. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the rear seal on the brake master cylinder disintegrated, which caused the brake failure. The vehicle was repaired. The dealer and manufacturer were not notified of the failure. The approximate failure mileage was 76,000.
