Is the parking brake the same as the emergency brake?
Consequently, what is the difference between a parking brake and emergency brake?
The parking brakes are the brakes you use to hold the vehicle stationary while parked. The Emergency brake is the braking system you can rely on to stop you when nothing happens when you push the middle pedal (or the right pedal, if you have the misfortune to drive a two-pedal vehicle). In most cars, they are the same.
Then, should I use emergency brake when parking?
The short answer: whenever you park! “Whether your car is a manual or automatic, the terrain is hilly or flat, you should use your parking brake every time you park,” writes Driver's Ed Guru. The parking brake is essential to your safety and those around you.
A conventional park brake or e-brake will use a cable for actuation. There is a system called a line lock that locks high pressure brake fluid in the lines to keep the brakes applied. Very uncommon outside of aftermarket. Newer systems are using electronic actuators to engage the park brakes.
