When faced with brake failure, the safest course of action involves a combination of downshifting, using the emergency brake, and steering to a safe area. This response is critical because downshifting helps to reduce speed by engaging lower gears, allowing the engine to provide some braking effect. The emergency brake, when applied correctly, serves as a secondary method to slow down or stop the vehicle, even if the primary brakes are no longer functioning. Finally, steering to a safe area helps avoid obstacles and potential dangers, reducing the risk of accidents as the vehicle comes to a stop. Each step taken in this scenario aims to gain control back and mitigate the dangers posed by losing braking capability. The other options do not provide a viable or safe method for handling brake failure. For instance, accelerating or simply coasting without addressing the brake issue would likely lead to more severe consequences in an emergency situation.
