In case of brake failure, what is one method to regain stopping power?

Using the handbrake is a reliable method to regain stopping power in the event of brake failure. The handbrake, also known as the parking brake, is designed to be used as an emergency braking system. When engaged, it applies pressure to the rear wheels, which can help slow down the vehicle.

It's important to engage the handbrake gradually to avoid lock-up and loss of control, especially in vehicles where the handbrake operates on the rear wheels. This technique is particularly useful in preventing a potentially dangerous situation if the conventional brakes fail completely.

Other options, such as shifting into reverse or pressing the accelerator, would not effectively slow the vehicle and could instead lead to further complications. Pulling the emergency lever, if meant to indicate a non-standard method of engaging the braking system, does not relate to a recognized vehicle operation procedure. Thus, utilizing the handbrake is the most practical and safer choice in a situation of brake failure.
