about every 20K miles. Warps the rotors very easily.
Live in Mountains.

That could be driving style. At 63k, I have only done
two brake jobs. Second time I went to pep boys and
bought new rotors for about 25 each. I ALWAYS use OEM pads.

I live in flat lands. I seem to recall that I had brake
problems when I came back from on of my Colorado trips though.
I did use low range coming down pikes peak!
