What should you do if your brakes fail while driving?

When faced with a brake failure while driving, shifting to a lower gear and using the emergency brake is a crucial action. This method helps to slow down the vehicle more effectively. When you downshift, the engine's resistance helps reduce speed, which is essential in regaining control over the vehicle. Additionally, the emergency brake functions as a backup system, allowing the driver to safely bring the vehicle to a stop. However, it’s important to apply the emergency brake gradually to avoid skidding.

Other options may not provide the necessary control in such a critical situation. Continuing to drive and pumping the brakes generally does not help in regaining effective brake function. Turning off the engine can lead to a loss of power steering and braking assistance, complicating the situation further. Pulling over to the side of the road might not be feasible if the vehicle is already out of control due to the brake failure. Therefore, the combination of downshifting and utilizing the emergency brake is the most effective way to manage a brake failure while ensuring safety.
