My GS was in for some warranty work in January, the nice dealer gives my bike a 'health check' and amongst other things they report rear brake pad ware at 30%, 2 months and exactly 1670 miles later it's in for some more warranty work and another 'health check' and this time the rear pads are 90% worn. Strangely, according to the nice dealer the front pads have gone from 60% to 70% worn in exactly the same time. For what it's worth I hardly use the back brake
Anyway, I'll be changing the rear pads my self in a few days and will report back on how much is left on them when I take them out.
