I have read that the Audi A8 has an electro-mechanical parking brake. How does this square with MOT etc, that is, not a mechanical link to handbrake mechanism. Other OEMs, or their suppliers are developing similar systems. Not really relevant but might be an interesting discussion point at MOT time?
Also I understand that Fiat have alloy calipers for the rear of the 'Weekend', made by Lucas, similar geometrically and function as the Sierra set-up.
