If your brakes fail one of the first things you should do is?

If your brakes fail, one of the first things you should do is remain calm and assess your surroundings. Shift to a lower gear to reduce speed, and gently pump the brake pedal to see if you can regain braking power. If that doesn't work, steer towards an open area or a soft barrier to slow down safely. Finally, use your horn to alert other drivers of your situation as you maneuver to bring the vehicle to a stop.
