The Prius has some of the strongest brakes I've ever seen. Those brakes coupled with the generator braking really do a good job of stopping the vehicle. Stopping is not an issue, even with the ones that supposedly got the accelerator pedal jammed by the carpet. One can hit the Power button and cut it off and/or flick it into neutral. When I traded my 05 in, the original brakes were still on and the car had 288k on it. It's a good vehicle.
