I was amazed also that I could go through the rear pads in just 7000 miles, I have never heard of that before. I only became aware of the problem when I heard metal to metal contact as I rolled out of the driveway with the engine off. Luckily I caught it in time and won't have to replace the disk, but its pretty strange. I wonder if the pads just disintegrated or something, I won't have the time to look at it good until next weekend. Anyway, what pads do you recommend?
