What is a necessary action to take when experiencing brake failure?

When experiencing brake failure, the most effective response involves shifting into a lower gear, using the emergency brake, and looking for a safe place to stop. This method allows the driver to reduce the vehicle's speed gradually and regain some control to bring the vehicle to a halt safely.

Shifting into a lower gear can utilize engine braking, which helps slow the vehicle without relying solely on the brakes. Engaging the emergency brake is crucial because it acts as an additional braking mechanism when the primary brakes fail. While performing these actions, it is also vital to search for a safe area to stop, which may include pulling over to the side of the road or finding an open area where the vehicle can come to a rest without endangering others.

This approach balances the need for immediate action with safety considerations, ensuring the best chance of preventing an accident while dealing with the brake issue.
