In a rear drum situation, the emergency brake cable runs directly to the brake shoes, bypassing the hydraulic brake system. In this simple, mechanical bypass, the emergency brake system requires no extra parts to control the brakes. Cars with rear disc brakes have a more complicated emergency brake system, sometimes requiring an entire drum brake system to be mounted inside of the rear rotor, called an exclusive parking brake or auxiliary drum brake.
When the vehicle has rear disc brakes without an auxiliary drum brake, a caliper-actuated parking brake system is used. With this system, an additional lever and corkscrew are added to the existing caliper piston.
When the emergency brake is pulled, the lever forces the corkscrew against the caliper piston, and applies the brakes, again bypassing the hydraulic braking system. Electric e-brakes are available on some cars today. Instead of having a pedal, stick, or center console lever, a small button on the dash signals an electric motor to pull the brake cable. Advanced electric brake systems utilize computer-controlled motors to engage the brake caliper.

Many people have the misconception that you only need to use the parking brake if you park on a hill or if your vehicle has a manual transmission. The truth is that you should always use your parking brake.
Whether you drive an automatic or a stick shift, or park on a hill or flat spot, using your emergency brake is good habit to develop. Using the parking brake on a regular basis helps keep it in proper working order.
It adds another level of security and reduces stress on the transmission and driveline parts. If you do suffer a complete loss of your brakes, slowly apply the emergency brake. While your parking brake is mainly used to hold your car in place, it can help you safely bring your vehicle to a stop in an emergency situation. There is one situation you should never use your hand brake.
Never use your hand brake to perform a drift maneuver. Learn more about quality brake parts , find your car part , or find where to buy your auto part today. It's that way on purpose so you have access to an alternative braking system should your primary brakes fail.
Your primary brakes work through a high-tech hydraulic system and are meant to slow your car to a stop. The emergency brake, on the other hand, is designed to hold your car in place. However, if your primary brakes fail, you can use the emergency brake to slow down and stop your car.
You should use your emergency brake every time you park. As the name suggests, you should also use your emergency brake in an emergency. If you can't stop your car, slowly pull up on the emergency brake handle or press the pedal down to come to a complete stop.
The correct way is to stop your car with your primary brakes, set the emergency brake and then place your car in park before turning off your engine.
If you put the car in park and then release the brake pedal, the transmission holds the car in place. That increases the wear and tear on it. Engaging the emergency brake first is easier on the transmission. These are usually button-operated and located somewhere on the center console. Some older vehicles may have a lever somewhere by the steering column under the instrument panel.
This mechanism is usually made up of cables underneath the vehicle that extend to spring-operated levers at the rear brakes. Some vehicles use separate brake shoes for emergency brakes while others connect to the rear brake callipers. Electric emergency brakes engage via motors at the rear wheels instead of the cable mechanism. Fully engaging the emergency brake locks the rear wheels only.
The emergency brake is designed to bypass the hydraulic braking system in case of an untoward failure of primary brake, be it disc brake or drum brake. When applied, the metallic cable connected to the emergency brake passes through an intermediate lever, enhancing the power of the pulling.
Then comes an equalizer that splits that power evenly between the brakes.
