Brake wear warning light--any way to tell which brake's sensor?
My wife's '11 GL450 with ~77K on it has started sporadically throwing the "brake wear" indicator. Thing is, the brake at all four corners have plenty of pad material left--I changed them all myself about 15K ago, and a visual inspection through the wheel spokes confirms that none of the outboard pads are remotely close to being worn. (Yes, I realize that an inboard pad could have been worn.) I suspect a loose connection or a partially failing sensor. Is there any way to tell which sensor is throwing the code through the computer? If I'm going to have to pull each wheel to do a visual inspection, I might as well just preemptively replace the sensors, but if I can isolate the problematic sensor first, that would be great.
