What should you do if your brakes fail while driving?

In the event of brake failure while driving, using the emergency brake gradually is the most effective and safest response. The emergency brake is designed to help you regain control of the vehicle when the regular brakes are not functioning properly. By applying it gradually, you allow the vehicle to decelerate without causing the wheels to lock, which could lead to skidding and loss of control.

Implementing this action gives you a chance to slow down safely and can help bring the car to a stop without creating additional hazards to you or other drivers on the road. It's crucial to be calm and focused in this situation, using the emergency brake carefully to avoid abrupt stops that could compromise your safety.

The other options present less effective or riskier responses, which highlight the importance of proper training and awareness while driving.
