New front rotors and pads for wifes 2006 honda element last week was $125.00 with a $25.00 mail in from Napa. I'm not messing with getting rotors turned for that price.

You can turn a rotor and still end up with a shimny or viberation because the cooling fins can rust away and throw the rotor out of balence. Twenty or thirty years ago you would never notice a unbalenced rotor because cars were not that smooth. Now cars are so refined you notice everything.
For most shops it doesnt make sence to turn when they can just slap on new ones and charge you the same $100 per hr. Plus mark up the cost of parts.
That makes sense, but not when I'm paying extra for better rotors in the first place. It's not a huge deal, but like kickstand said, it's just a waste. Why fix it when you can buy new??

I can't remember the name of the shop, it's the white building between mcds and kmart, something muffler shop??? Beavers said they turn them but told me no when I brought the rotors in; carquest said they couldn't be turned either. This was also for rotors on two different vehicles, 1996 chevy 1500 and 2006 colorado

The sad part is i'm not even that old, 24, we used to turn rotors and drums all the time in auto. Now most people I talk to have no idea what i'm talking about when I mention it

Maybe it's not true now but I was always under the impression you don't need to replace the rotos/drums when you replace the pads/shoes, unless there was an obvious problem. I usually go about 2 changes of pads/shoes for every one change of rotors/drums, on the 96 anyway.

On the flip side, as a kid working in an auto store I wish I had a dollar for everytime someone brought in a metal to metal worn rotor and asked to "just clean it up a bit". We had some of the really trashed ones hanging on the wall. Like the guy who put new pads in so ignored the noise and he kept driving until the rotor wore down to the fins. (Note: it works better if you put the friction side of the pad against the rotor.)

In the old days before the rotor eating semi-metalic pads, you could go through several sets of organic pads on the same set of rotors. Rear drums almost never needed to be replaced unless they went metal to metal.

Don't all rotors have a bunch of rust on the edges a few days after they are installed?

Even if you do find a place that will turn them if there is enough material there, the fuckstick making $8 an hour will probably fukc them up anyways. Had this happen to me on a rotor that listed $120 at the dealership, and wasn't available at the aftermarket level yet.

Most rotors from the OEM are coated around the hub area and the vents. Most of the rotor hub rusting is a thing of the past, at least until they just get pretty damn old.

Sadly I work with a fuckstick at a dealer who's been doing this for 30 years and he still can't turn a rotor without screwing it up.

Some do but what I was getting at is the ones that have pitting and you can't turn it out without getting under spec.

How long ago is "a thing of the past"? Had to replace the rotors on an 05 because they were literally rusting to pieces from the inside out. The rotors on my Dana 60 put into service in 1995 are still in good shape.

'05 what?

Most higher end vehicles from 2008 on up have had coated rotors. Most of the cheap econoboxes now get it, but it depends on what MY the new vehicle launch was for.

More then likely your Dana 60 rotors were casted in USA and not China...

Typically any model that has a new model year launch of 2008. Of course, there are always exceptions to the rule and finishes don't last forever.

When I was a broke 16 year old it seemed worth the small difference vs buying new. Now I'm not going to stretch a 30 minute brake job a day or two because I'm waiting to get the rotors back... Ain't nobody got time fo that.

I turned rotors all the time at the dealership. But, I remember us having to buy an "on car" brake lathe because when the Colorado/Canyon came out, that is the only way the rotors could be turned. Something about the rotor being part of the hub or something. Never ended up doing rotors on a Colorado or Canyon.

Unless the rotors were really rusty, I think they were just lazy.
