Finally today I decided to do my rear pads for the first time at 170K, Wow!.
It was very much a piece a cake. I had began to hear a squeak here and there when I braked so I figure it was time, sure enough the pad was even with the alarm terminal when I removed it. My front ones were done at 144K. Never had brakes last that long and it's most like attributed to all my highway miles . I also used the Nissan value pads, much cheaper and they came with shims and a little bag of moly to dab in between. Will se how they turn out.
