What are spring brakes?


Spring brakes are powerful springs that are held back by air pressure. If the air pressure is removed, the springs apply the brakes.

Spring brakes are large springs full of air pressure. If the air pressure is increased, the springs apply the brakes.

Spring brakes are large springs forced closed by air pressure. If the air pressure is increased, the springs release the brakes.

None of the above.
