What should you do if your brakes fail?

Shift to lower gear
Push the brake pedal
Use your emergency brake
Press the gas pedal

The correct answer is: Use your emergency brake

If your brakes fail, it is important to use your emergency brake immediately to bring your vehicle to a safe stop. Option A, shifting to a lower gear, may help you slow down but it will not stop your vehicle completely. Option B, pushing the brake pedal, will not be effective as it relies on the brakes working properly. Option D, pressing the gas pedal, should never be done if your brakes are not working. It will only make your vehicle go faster and potentially cause a more dangerous situation. Therefore, using your emergency brake is the best and most effective option in this scenario.
