In 2003, my truck failed inspection in England due to "rusty rotors". He showed them to me, they didn't look bad to me but then I've no basis to judge it. I saw some rust color and very light pitting - didn't look terribly bad to me. They said they replaced the rotors - do not know what brand they may have used.
As you long-timers may remember, I was in England for a few years, the truck was subjected to roads that were wet and salted nearly every night for most of the winter. Then I went into the desert, little rain and high heat. I've been back in Northern VA for a year now, it's been a bit wet around, and last summer was pretty humid and warm.
Here it is, 2009, and I took my truck in to my trusty mechanic because of brake issues - emergency brake locking up when it's wet, a bit of a rough and maybe rhythmic feel as I brake, and twice now, a double clunk as I am slowing to a stop.
I'm told the rotors are really badly rusted. *This* mechanic I trust (though I will look at the rotors once the truck is done). What are the chances that they never actually replaced the rotors back in 2003?
My brake pads finally wore out though. I've got nearly 70,000 miles on the truck now over 9 years, so I'd say that's not half bad :)
