Hi All, I wanted to get other's opinion. I went to longo before of warped rotors(pulsating brakes). Anyway, they said they replaced the rotors, but it would appear that they simply resurfaced the rotors. Granted this was done under warranty and I didn't have to pay for anything, but the rotors keep warping and this is gonna get expensive...what do you think? I suspect they were just resurfaced because of the cross cutmarks...

TIA for any help

Show a pic of the side of the rotor the best you can. Do the internal vents have rust coloring to them? If yes, then they resurfaced them. Some places resurface even new rotors-especially if they have a on the vehicle machine which cuts it true to the hub.

No those are new rotors! I Work for Lexus and when you machine a rotor it doesnt make that design! Those rotors are new from the factory never been machined!

Not necessarily true; though yes that criss cross pattern is not from turning, many that truly understand how to turn rotors understand and place a criss cross pattern on the rotor to roughen up a tad to assist with the brake pad break in.
I will say that the pattern in the picture does appear machined though, a bit too good for a rotor brush.
But, take a look at the outer edge and also the small portion of the visible hub, both which appear to be rusty in color. It could also be the angle of the picture. Either way it is easy to tell by just looking at the hub and internal vents. Bit premature to judge without seeing another angle.

Those look new. My 07 GX with only 11,000 miles on it still has that pattern in the rotors. Guess I don't use the brakes to much?

Why not have the thickness measured at another shop? You can do some research on what the thickness should be for a new one and if these measure less, then you will know for sure.

Just a thought - not sure if its worth the trouble.
