94 Brake Rotors-duped or not dupped?

[IgotTwo]

I’m not sure if I got duped, but I will take it well, if I was.
1994 XLT Explorer
I had a front brake squeal only on a slow roll. So I pulled one of the wheels. The pads looked good from the outside and no visible rotor marks. A quick cleaning and rail greasing whatever I could, didn’t work. So I pulled the calipers.
BOTH inboard pads had a side to side crack 3/4 of the way down from the top??? They looked like mirror images??? The pads were still pretty full, with even wear and had about 18K on em. So I ripped everything down.
I bring the rotors to get turned. After the guy turns em, he tells me the rotors had “low spots,” suggesting they were warped. Yet the old rotors were cleanly turned and according to him still within thickness specs.
I did get new rotors....and bearings...and seals...and so on.
But I was thinking (which is sometimes dangerous): If the old rotors were turned and within specs...did I really need new rotors? I’m thinking the lathe did the trick on the “alleged” warp? I hope I don’t need a molecular metallurgist for this one.(just kidding)
Any thoughts?
Thanks

if the rotors were within spec you didnt need to get new ones unless yuor mounting surfaces were warped

James,
Thanks for the feedback.
Why did I think I already knew that...but I did promised I’d take it well.

I should know better, but I keep making the same mistake:
I have to stay away from these shops where everyone is mentally paralyzed without a computer number and need printed confirmation for everything they do.

I gotta find a place where everyone who works there looks like ZZ Tops and they don’t whine about everything.

Thanks again

no problem i think we have all benefitted from each other at one time or another we are all here to help each other out

Sometimes it borders on being criminal. This may be a goofy example but:
While I going through my brake job, I needed “speed nuts” (aka - “brake drum hold downs”, “hold down washers”, those washer type things you wack on with a deep socket to keep the locking hub on)

After telling “the manager type parts specialist” that I needed them for the front locking hubs on a 4WD Explorer, he tells me I “really did not need them” cause ”they only come through from the factory.”
Aaaannnk! Wrong answer!
Like I’m the one only one in NJ that has locking hubs!
I’ll have to let him change my front tire and he can watch that thing fall off and roll down the highway.

I’m not a mechanic so I pause to consider, I maybe missing something. The better answer is to get out the book(s) so you have a good “BS” filter.
Hey! that’s the best way to learn..(and hanging out here haha)

uh oh

New...rotors?

Surely you didnt pay even close to what you could have bought the powerslot rotors for?

HA HA
No, I just got plain old "fine American rotors"
They weren't expensive and its always best to error on the side of conservatism with brakes Hey! Everything is a part....fix it right!
I hope I didn't seem like I was whining ..just trying to get smarter. One thing is for sure: I do need a better "BS" filter when I go to some of these part places.
