What owners wrote

Was driving my mazda cx-9 in afternoon traffic when the car in front of me applied their brakes to stop. I went to apply my brakes and the pedal was hard and nothing happened...the car would not stop. I then placed my other foot on the pedal in order to apply more pressure and still nothing. Heard a hissing noise and then realized this car was not going to stop. "scared the hell" out of me as I watched my car hit the car in front of me. Thank god I was not going fast or this could have been tragic.
