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 do you check spring brakes?
With the spring brakes engaged, put the truck into first gear, and let off a little on the clutch. If it pulls, but does not move, your brakes are in working order. If the vehicle moves, there's a deficiency which needs to be corrected.
