My brakes are hard as a rock cause me to use more force on the brakes to stop and there is hissing coming from brake booster when I apply the brakes on my vehicle causing prolonged stopping distance called ford and they said there was no recalls on that vin which their ‘recalls is vin specific’ yet all the vehicles use the same brake booster that is installed on this vehicle. It was hard to stop even going at low speeds under 10mph
