If your brakes fail while driving, the best course of action is to pump the brakes and, if that does not restore their function, downshift and use the emergency brake. Pumping the brakes can sometimes restore pressure in the brake system by re-engaging the brake line. If this method does not work, downshifting allows the driver to reduce speed by gearing down, which engages the vehicle's engine to help slow it down. Using the emergency brake should be a last resort since it can cause the rear wheels to lock up if applied too suddenly, leading to a loss of control. This approach helps in managing the situation effectively and provides a chance to regain control of the vehicle, whereas other methods like immediately pulling the handbrake or driving to a mechanic without first attempting to slow down may not provide a sufficient response to the emergency.
