How does one accomplish getting brakes to a trailer using air brakes?
Why do you feel the need to have air brakes on the trailer? In all likelyhood your chassis is prewired for electric brakes. In most cases there is a plug under the dash for the controller and the trailer hitch socket at the back already contains the wires needed.
Since the manufacturers prewire for electric brakes they must feel it's more than adequte to do the job. Most controllers are setup to handle up to 4 axles. That means they're rated for nearly 30,000 lbs.
I would check with Freightliner before making any modifications to add air powered brakes on a trailer. I know they don't like the 4 down braking systems that tap into the air manifold just to power a single cylinder. It may be a case that the air pump isn't powerful enough to take on the added load.
