Default rotors

Is there any possible way a truck with 130,000 miles that has never had the rotors turned needs new rotors for a brake job?

Rotors typically last 50-70K miles, and can extend to over 100K miles if they've been properly maintained and resurfaced. So at 130K miles it is very likely new rotors would be needed if they've never been resurfaced.

most shops wont bother to turn rotors anymore and they dont want come backs so the default is to replace the rotors. I did my brakes around 130k and I felt like it was time based on the grooves developing

These days, I always just put new rotors on. When I replace my rear brakes, I am using OEM pads and rotors.

Depends how thin the rotors are. They need to be measured to know for certain.
If the miles are a lot of highway, the brakes may not be used as often as a city truck.
It would be nice to have them trued if nothing else, replacement based on inspection.

Not sure if you are disagreeing with a shop that wants to sell new rotors or if you are planning a brake job this weekend and want to know if you should purchase rotors due to age.

I get 90k+ miles before a brake job is needed. At that mileage I replace the rotors since I don't want issues, and it costs very little extra versus turning rotors.

If you have 130,000 miles on them, change them. You have gotten your money worth and them some out of them already.

Rotors are not a time or mileage based replacement item. If they are within spec and not grooved or corroded, there is no reason to replace them. Certainly rotors on a vehicle that has been predominantly used on low traffic freeways could last that long or much longer.

130,000 miles is pushing it, even for a very easy driver that lets air resistance do a good bit of the braking. I'd check the remaining thickness before calling them good.

You need mass to absorb the heat generated by braking as rotors don't just release it to the air right away. That mass acts as a buffer between the amount of braking you need to do now and the time the rotor needs to shed the generated heat. The less mass you have, the hotter the rotor gets during a braking event. Wear off too much rotor mass, you significantly cut the time it takes to get to temperatures where the pads will start to fade.

I haven't on any of my vehicles but my wife in her 2013 CX9 went right at 150k on rear brake pads and when I changed them I did not touch the rotors. She did a lot of highway driving at that time.
