A spring brake system includes a service brake chamber, a spring brake chamber adjacent to the service brake chamber, a wall separating the service brake chamber from the spring brake chamber, a shaft, and a device. The shaft extends from the service brake chamber into the spring brake chamber through an opening in the wall. The device is disposed along the shaft through the wall, the device being configured to: i) allow air to flow from the service chamber into the spring brake chamber, and ii) prevent air from flowing from the spring brake chamber into the service chamber. The air is within a range that is sufficient to reduce a pressure differential between the service brake chamber and the spring brake chamber. The air is also within a range that is sufficient to generate an anti-compounding effect.
