Yes, you experienced an ABS activation. The system rapidly pumps the brakes for you, and your system is held active as long as you are stomping down. It feels like a vibration, the pedal drops down a bit and it's odd feeling. If you're in an ABS activation, just stay stomped down until it deactivates or you regain control of the vehicle.
