I had a temporary brake failure at 25mph with a hard brake. I had a car pull out in front of me and I had to hard brake. The brake pedal was soft and went all the way to the floor with no braking until it was all the way to the floor and it finally worked with a sudden stop/jolt. When this happened it made a low sort of almost vibration sound. I did not feel a vibration in the brake pedal though. The brakes worked well before that and after that. If the brake would have not suddenly grabbed when the pedal was to the floor I would have hit the car. I was going about 25mph. I know what it sounds and feels like to have worn brakes and rotors. This was not it. Again it was a temporary failure and after that the brakes are their normal firmness and responsiveness. This is definitely a safety hazard as it very unpredictable.
