Factory brake rotors cracking already (under 30k)

[braindead0]

I was airing up the tires on my wife's 2001 PT, and noticed what appears to be a hairline fracture in the brake rotor.

Are these rotors total junk or what? I've got nearly 80k miles on my S-10 and the rotors (original brake pads still have 3/8" left!) are still fine.

Whats a good suggestion for quality rotors? Not looking for anything fancy, just good quality rotors.

Wearing in one thing, but cracking ? I would take them off and get a closer look.Usually the only way they crack is if you have them turned and you go below the minimum thickness listed on the rotor.
As far as a quality rotor, I've never tried them, but check this out:

It looks like a hairline on the rotor, I didn't put my finger to it (bad idea..oil and all) so I'm not totally sure. But it sure does look like a crack. The rotors shouldn't have been turned, but who knows as we got it used.

If you think its cracked I wouldn't worry about oil, check it out right away.

Most brake rotors today are made as cheap as possible even on high end cars. Look how they rust. I have Powerslot rotors on mine nd even though there are cheaper ways to go I think they will last a long time plus no more rust. I also think if you hate cleaning the brake dust off your wheels the Raybestos ceramic pads are the best. They cut the dust by 95 %

A mechanic would most likely call the cracks "heat checking." This is a fairly normal occurance on rotors. If your brake pads are not worn out, don't worry about these hairline cracks. When you change your pads, have the rotors turned and you will be fine. You only need to change your rotors if they are past the minimum thickness. The minimum thickness measurment is cast into the back of the rotor. Many owners are spending the money to replace their rotors when it may not be necessary. On the other hand, if you are still concerned, take your car to a good shop (like Les Schwab) and have the rotors checked.

If anyone has more input on this thread, please give us your opinion. Thanks.

I think 'heat checking' might be the best term for it. Braking isn't a big problem, brakes seem fine. I'll have the wheels of this weekend anyway and I'll take a closer look. I may just buy some powerslot rotors, just for peace of mind..
