The braking distance is the distance you travel with your vehicle from the moment you step on the brake until you come to a complete stop, and is something mechanical that depends on the condition and speed of the vehicle, among other things. The reaction distance, on the other hand, is the distance the vehicle travels in the time it takes the driver to react, which will depend on the driver’s mood, physical condition and external factors. In this case, it is something biological that depends on the driver, and not on the vehicle.
