When I took my '04 Edge 2WD 3.0L with 58,000 miles in for tires, they checked the brakes. They told me my rotors were worn to the point that they couldn't be turned, and had to be replaced. I knew that was bull, since I replaced the original, factory-soft pads well before they were even close to metal, and I replaced them with the best ceramics, which still have more than half their life left. So my rotors have NEVER been turned, and they should be well within spec. The tire place re-measured the rotors with me watching, showed me the measurement, and then showed me their book, which indeed indicated that for that measurement the rotors needed to be replaced. The spec was something like .987 or .985...don't remember, exactly. This must mean that the specs in their book are wrong, right? Or, since they could only look up "Ranger," are the rotor specs different for Edge?
Any insight appreciated.

 

For a 2001 Edge the factory manual states the minimum (discard limit) is .985 and 1.023 to still be serviceable. However, the actual number should be embossed somewhere on the rotor.

 

I'm not sure on the Ranger, but many vehicles these days dont allow for much wear. as already stated, there is a turn to and discard thickenss. I highly doubt the shops book is wrong.

I just put new rotors and pads on my 03 Edge and I belive they were $34 a piece so either way, its not that spendy to just drop a new set on anyways.
