Total brake failure is rare. However, if your braking system fails, don’t panic. Look for an escape route or something to slow you down. Pump the brakes hard and fast; you may be able to get enough braking action to stop the car. Downshift into the lowest gear so the engine will help slow you down. Apply the parking brake gently and gradually, but be prepared to release the parking brake quickly if the car goes into a skid. Use the hazard lights or the horn to warn other drivers. Never allow a head-on collision. Head-on collisions are often fatal.
