I have an 06' Lariat crew cab 4x4 with 44K on the odometer. I just went through a MD state inspection a month ago and passed with no problems.
I bought the brake pads online and took my rotors to pep boys to have them turned.
The guy I left them with at the counter measured the thickness and said he did not see any problems with turning them.
I got a call this morning from another guy who said they would be too thin after turning. The rotors weren't warped, I checked the run out with a dial guage before I removed them from the axle. There was about a 3/8 inch pad left on the fronts and the rears were even thicker.

He said they would have to order new rotors at a cost of over $300 for their brand and over $400-500 for a name brand.

You guys think this is a scam and a half or what?? How much material is usually removed for a re-surface on rotors that aren't warped?

I was trying to get this done over the weekend so I can get my truck back on the road today.

 

I never turn rotors when doing my own brakes. The only way I would turn them is if they have some grooving. I clean them and put the new pads on and have never had a problem. Got 80,000 miles out of the last set of pads.

If a rotor is warpped, it's my opinion, if you make it thinner by turnning it, it will warp even quicker. It's a weakness in the metal.

That seems very high for 4x4 rotors.

if it were me, I would pick them up and put them back on.

 

You may not have had any runout when you measured the rotors BUT whats more common is thickness variation. Generally runout would be measured on the outside surface of the rotor but it is my experiance that the INSIDE surface usually needs 2x if not more material removed then the outside. Sometimes it may appear that you will have enough material to work with but you dont really know for sure untill you start machining.

 

I would take them to a real shop and see what they say. Pep Boys is a joke. They did the same thing to me before.
