    About 40% of the time, my toyota prius doesn't want to stop or slow down when the brakes are applied. Under these conditions, i have to apply the brakes hard and then the car will slow down. It feels like the car wants to "run away" when the brakes are applied. It exhibits this behavior in many circumstances: stopping at a stop light, slowing down on an expressway, or slowing down on a city street. *tr updated…
