The component that failed was the Brake pedal, it was unresponsive while driving on the freeway, it was hard to push and the vehicle would not come to a complete stop. My safety along with my daughter was put at risk due to nearly colliding into several vehicles due to not being able to stop vehicle. I had to tow the vehicle to the nearest shop where it is currently. During the incident the brake light came on. The shop where the vehicle is currently is stating that it appears to have a faulty Brake Vacuum Pump.
