What Are spring brakes on a tractor trailer rig?
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.

How can you check that the spring brakes will come on automatically?
To check that the spring brakes will engage automatically, start by ensuring the vehicle is on a level surface and the engine is off. Release the service brakes, and then fully charge the air system to the manufacturer's recommended pressure. Next, turn off the engine and observe if the spring brakes engage by checking for a noticeable change in the brake pedal feel or by inspecting the brake indicators. Lastly, you can also manually pull the spring brake release valve to confirm that the spring brakes are functioning correctly when re-engaged.
How do emergency brakes work with a school bus air brakes?
They have a spring brake system. When the vehicle air up, air is metred to the spring brake chambers. When it reaches 60 psi, sufficient pressure is pushed against the spring to release the spring brakes and allow the vehicle to roll. When this air is removed - either by pulling the tractor protection valve or by a failure of the air system - the springs push back down on the spring brakes and lock into place.
