The parachute works well because it creates a large drag force at high speeds, slowing the dragster down more effectively than traditional braking methods. It is not because the dragster does not have any brakes, there is no rolling friction, or the driver has no time to apply the brakes. The deployment of the parachute may be part of the show, but that is not why it works well in terms of stopping the dragster.
