Hi,
I know that the front brake pads have a pad wear sensor (which is a feature that I find to be pretty rare on newer cars), but how will I know when the rear pads are going? I don't think my rear pads have been changed in something like 60K city miles and I'm worried that they're going to wear so far down that they pad backs will start scraping the rotors. If you tell me that the only way to know is to take the wheels off and have a look, then so be it. It's damn cold though, and I don't have a garage space to work in now, so it'd be nice if Mercedes engineered some kind of warning system into the rear brakes.

Alex
