Whether you have a disc brake system or a drum brake system, you have a parking brake that is responsible for locking your vehicle in a parked position. The parking brake, also known as the emergency brake, is applied independently of regular brakes and is engaged by either pulling the parking brake lever or pressing a special pedal. Most motorists use the parking brake when parking on a steep hill. However, the parking brake can also be used to stop suddenly and prevent an accident from occurring. There are three types of parking brakes that use a ratchet locking mechanism: stick, center level, and pedal. Each type of parking brake depends on the style of driver’s seat, and each operates differently depending on the brake system. You should always consult the owner’s manual to determine the correct position of a disengaged parking brake and whether or not your parking brake needs an adjustment.
