With properly operating brakes, engine braking will never stop faster than applying pressure to the brake pedal. If applying pressure to the brake pedal can lock up the tires (or engage the ABS system in cars so equipped), then no amount of additional braking force (such a engine braking OR additional pedal pressure) will stop a car any shorter.
your doing it again your bad for my blood presure.
and i still think puting the car in rever will stop the car quicker.
why dont we fit retro rokets and parachute. or just drive it into a wall that will stop a car quicker than any brakes.
