OK, Here's a guess as I really don't know how the hazards are activated under severe braking but....
What happens if you sit in the car with the engine running and press as hard as you can on the brake pedal? I know we are talking French design here, but the easiest way would be to have two contacts in the brake light switch, activated at different amounts of pedal travel.
