My rear pads wear much faster than my fronts. I have plenty of meat on the front with over 15,000 miles on them. I have a Speedmaster though and I think that has something to do with it since I have twice the breaking surface of an America. I use my front and rear together when stopping but when following Wendy I tend to just tap the rear to bleed off a little speed when needed so I stay with her and not pass her. I don't know if that is of any help to you or not but there it is and I seem to wear mine faster too.

I learned all I need to know about life by killing smart people and eating their brains.
