| Description of the problem | Truck is a 2014 f150 5. 0v8 with ~50k miles. While vehicle was in motion at highway speeds ~65mph, brake fluid warning light comes on. I test the brakes by gently depressing the brake pedal, but pedal continues with no resistance nearly to the floor. Brakes are almost completely ineffective and would have zero ability to stop the vehicle in an emergency situation. I throw on the hazard lights and cut to the shoulder and have to manually downshift the transmission to slow the vehicle. Situation could have been much more serious as i was in moderate traffic. I popped the hood and immediately notice the brake master cylinder reservoir is completely empty. After inspecting all brake lines front and rear and checking all bleeder screws are closed, no visual leaks are present. As i was 100 miles from home driving my wife and child home at night, i had someone bring me some brake fluid to top off the reservoir. After filling the reservoir and bleeding the front brakes, brakes seem to stay tight. I drive ~10 miles and the brake fluid warning light flashes again at highway speeds. Pull over again and notice zero fluid again. Visually inspect all lines, master cylinder, booster, etc., no evidence of leaks. Top off the reservoir to limp the vehicle to a safer location. Notice the engine starting to sputter and fluid completely gone in another ~10 miles. Obviously the master cylinder has failed and is leaking into the booster which is affecting the vacuum in the booster. These are the exact same symptons listed in safety recall notice 16s24/ nhtsa recall 16v-345, however this does not cover 5. 0 v8 motors only 3. 5l ecoboost despite the same brake components being used. So far over a quarter million trucks have been recalled. Apparently newer 2015/16 f150s are experiencing similiar issues as well evidence of a large defect in newer model f150 braking components. |
