go figure this. I was hearing "scraping" noises so I decided that @74k miles, it was time to check/replace the pads, especially the front. I mean that is what USUALLY wears first right?? Well,....the front pads were fine!! about 60% left on em. Well, I then decided that this noise was somethin' else. But the annoying scraping noise came back. Ok. so I checked the rear pads. OMG...the driver side was worn to the metal. The passenger side was worn but not equally to that of the driver side...(go figure). Well all replaced now. The rotor was not too bad, so replacement was not necessary. Oh,.. the turning of the rear cylinder thingy, to make room for the new pads was interesting. Thank goodness for the internet.
