Went ahead and changed the front pads, after over 2 years they had about 30% life left. I have never heard of pbr brand pads but I checked the bag and sure enough that is what the guy at the store gave me. Sounds like they are great brake pads. The onlly thing is that they include asbestos, but I guess that it is safe.
