Air brakes are a completely different animal than hydraulic systems. Air brakes use air pressure instead of hydraulic fluid, and if you have air brakes there are some inherent differences in how you should use them, vs hydraulic. Most coaches with air brakes will also have some sort of engine braking system IE: Jake Brakes, which are critical to know how to use if you are coming down a long steep grade. The short answer to the OP's question, is no fluid, only air.
