Re: Disconnect the neg battery terminal?
Usually, the only reason they say disconnect the neg lead is so that you don't accidentally short something out while you are removing it. I wouldn't worry about the brake wear indicators, it's only a wire in the pad which shorts to earth when the pads are to thin, all that will happen if you short the lead to earth is the light on your dash will come on. I very rarely disconnect the battery to do work on the car but I am always extremely careful with any live leads.
