They're not just on tractor-trailers - you'll find them on most air brake equipped vehicles. Spring brakes can be described as parking brakes. That's the simple answer. They are brakes which are held down by a spring. When air pressure is introduced into the system, via the service air system, the air pushes against those brakes, forcing the spring to compress, and releasing the brakes. The air pressure must remain constant in order for the spring brakes to remain released.
The brakes will remain on, air pressure is required to release the brakes
With respect to navigation, a bearing is the direction from one's vessel or aircraft to an object or position. It can also be used as a reference point, such as a line to remain clear (or north or south) of.

remain calm and continue driving in the same lane. Begin to apply the manual emergency brake with your hand, lightly at first to determine the strength. You dont want to lock up the brakes, so apply the emergency brakes in spurts and make your way to the side of the road.
A parking brake is any system which is intended to be used when a vehicle is parked, whether it's a spring, a cable, or any other device. A spring brake has a spring which constantly presses the brakes to remain engaged.. during normal operation of the vehicle, a quantity of air is supplied to push against the spring so the brakes remain released. Air brakes simply mean a braking system which uses air for actuation instead of fluid.
