Nova Scotia Driving Test Practice: Ace your driving test

What should you do if your brakes fail while driving?

1. Accelerate to gain speed

2. Use the parking brake immediately

3. Pump the brake pedal to build up pressure, shift to a lower gear, and use the parking brake if necessary

4. Turn off the engine

The correct answer is: Pump the brake pedal to build up pressure, shift to a lower gear, and use the parking brake if necessary

When faced with a brake failure while driving, the appropriate response is to pump the brake pedal to build up pressure, shift to a lower gear, and use the parking brake if necessary. Pumping the brake pedal repeatedly can sometimes restore enough pressure in the braking system to allow for some braking power, which is crucial for slowing down the vehicle. Shifting to a lower gear is advantageous because it allows the engine to assist in slowing down the car through engine braking, which is an effective method to reduce speed when the brakes are not functioning properly. The use of the parking brake can be a last resort; however, it should be used cautiously as it may cause the rear wheels to lock, potentially leading to a skid. The recommended actions focus on maintaining control of the vehicle and gradually slowing down in a safe manner, thereby minimizing risk to the driver and others on the road.
