Brake light comes on while driving then no brakes! unless you push the pedal real hard then it makes a grinding sound! when you stop vehicle stop the engine and let it sit for a few minutes, then start it, the brake light stays off and everything works fine again! this happened twice! the first time was march 2018 we then took to dealer and they charged to install new booster and some other device. today jan 4th 2019 the same thing happened!
Started to notice violent shaking in the front of the vehicle when the brakes are applied at interstate speeds. the 2015 expedition 4wd has 19,000 miles on the odometer. at very low speeds there is the same shaking of the front brakes---but much less noticeable apparently due to the low speed. trying to schedule warranty inspection at local ford dealer.
