On a T30 brake can, there are two chambers - the service chamber, and the emergency chamber. In the brake chamber, there is a spring.. when decompressed, it rotates the S-cam to lock the brakes. This is your parking brake. When you release the brakes, the emergency chamber remains constantly supplied with air to compress this spring, effectively releasing your brakes. The service chamber counteracts this, allowing you to utilize your brakes, but only when air is supplied to it when you push on the treadle valve.
