Brake light came on lost all use of brakes whithin 5 minutes while driving 70 mph on highway. I was driving with the flow of traffic on a flat surface.
Brake failure, no brake warning lights. Peddle provided some braking initially, then peddle fades to floor and braking deminnishes to not able to hold vehicle to complete stop, even at idle speed. Pumping peddle will restore same sequence. I would think this would be extreamly scary to novice drivers and cause injury, death or collision with high probability. Especially with absence of warning lamps indication. First time problem noted on near zero degree f. Morning shortly after leaving early am on highway. Suspect problem to be master brake cylinder. Brake fluid level has not changed, search for external leaks in braking systems revealed no visible leaks. Vehicle currently in to service this at francios Ford bellville WI.
Low brake fluid light came on, with in one mile the brake pedel went to the floor with very little stopping power. Brake fluid resevior was completely empty. Added brake fluid as warning light recommended, drove 1 mile and brake fluid resevior was empty again. Luckly I was driving in town with very little traffic.
Driving on interrstate 70 at 65 mph, I had several alerts begin flashing ranging from check 4x4, hill assist failure, 2h, parking brake and many more. In addition I lost power steering, brake lights and turn signals. I was able to drive truck home. This happened 4 more times. I called dealer and they suggested I drive it to their establishment some 20 miles away. I did not feel safe and contacted roadside assistance to tow the truck. I had to beg for a loaner one week later I received a call stating the technician needed to drive the truck to see if the same alerts happened even though they found 12 plus alerts when they analyzed the truck in their shop. I allowed this to occur as I wanted answers. I received a call today stating they had found the problem, a wire had became corroded in the steering column causing all the alerts to malfunction. They are replacing the entire column and my truck will be completed by Tuesday. I had purchased this truck just 4 months prior and have been a loyal Ford customer for 30+ years.
