Cheap rotors????
I have basic/stock rotors on all four wheels. They are fairly new, less than 1500 miles on them. After driving for a while I start to get an intermittent rubbing sound from my left rear. It only happens when the breaks and wheels are hot. Could these rotors be warping when they get hot? Are they just cheap and poorly made?

What happened to the original rotors? If you know where they are, I'd put them back on! You will not find a better quality rotor than what GM put on. My rotors have about 120K on my rotors with absolutle no signs of wear whatsoever and about the same goes for my other 2 '73's.

There could be several things that would cause this sound besides the rotors.
Bearing run out, bearing failure, parking brake hardware issue, bad pad set (grease on the pad), u-joint and so on.
There is a cheat way to check the rotor/bearing run out if you don’t have a dial indicator.
Pull the pin on the brake pad and paint it. Then take the car for a drive and see how much is worn off when finished. If you have a large area of paint missing
When the car is making this noise you can jack up the car and sit it on a jack stands. Make sure you let the a-arm rest on the jack stand, if you don’t you can over extend the capability of the u-joint. Then listen for the noise and see if you can find it.
