Technically, the "Parking brake" can be used in an emergency but it isn't primarily meant to be an "emergency" brake.
I've had the throttle stick open before. That is a sobering experience. I've never had brakes totally fail but have had them perform well UNDER my expectations. That is a bad feeling as well.
