There was an article in the TDR mag a few issues back that was pretty positive. With 92,000 miles on my truck, I am about to go through my second set of front rotors. I keep the rears adjusted, must be the way I drive with lots of stop-n-go traffic. I called Glen at EGR; what he said made sense so I have a new set of EGR rotors and pads in the garage ready to go.
