I had to have mine rebuilt a few months ago, had it done by a company in Sydney. My brake mechanic removed just the module not the pump and pipes and mailed it off to the repair company. It took about 3-4 days and cost about $275 approx, a bit better than what Ford quoted ($6,600 supply only). The company are on the net so you can search or contact via:-

Hope they can help you out.
