I bought my bike used, it is a former RT-P, but I have the maintenance history and the front brakes were replaced about 47000 miles... the rears had not been replaced, and I was warned in February that the rear pads would require replacement this year. I got a set of pads from ebay last month but had not checked the rear except for the rotor and it was within spec and looked good.
Last week, I was reading on one of the forums that changing the rear brake pads was less than a 30 minute job, so over the weekend I planned to change them. When I finally got to it on Saturday morning, I found that the rear pads were within a few microns of being metal to metal! I was glad I had not delayed it any further.
The bike just went over 60,000 miles on it and this is the first time the rear pads have been replaced... I hardly ever use the rear brakes... this new set of pads should last at least until 100,000 miles, but I certainly plan to check them a little more often.
