A driver is experiencing a sudden brake failure. What is the initial action the driver should take to try and stop the vehicle?
- AShift the transmission into 'Park' or 'Reverse'.
- BSteer sharply to the side of the road and hit an object.
- CImmediately engage the parking brake fully.
- DPump the brake pedal rapidly and firmly.
Show answer & explanationAnswer & explanation
Correct answer: D. Pump the brake pedal rapidly and firmly.
Pumping the brake pedal can sometimes build up enough hydraulic pressure to restore some braking ability. This is the first step before resorting to other emergency braking methods. Engaging the parking brake fully at high speed can cause a skid, and shifting into 'Park' or 'Reverse' can severely damage the transmission and lead to loss of control.
Why the other options are wrong
- A. Shifting into 'Park' or 'Reverse' at speed will severely damage the transmission and cause loss of control.
- B. This is a last resort to avoid a more severe collision, not the initial action for brake failure.
- C. Engaging the parking brake fully at speed can lock the rear wheels and cause a dangerous skid.
Brake Failure Response
In the event of brake failure, the first step is to pump the brake pedal rapidly and firmly to try and restore hydraulic pressure. If that fails, other methods like using the parking brake gradually or downshifting should be employed.
- Pump brake pedal first.
- Gradually apply parking brake.
- Downshift to slow vehicle.
Memory trick: Brakes fail? Pump, park, and downshift, for a safe, slow drift!
