noisy rotors... Over the past couple weeks, i've noticed friction noise in both my rear rotors. Now i pulled the wheels and checked and there is a little movement (like 1-2mm) between the pad and rotor when you turn it. It's flush and then will slightly gap very very little again like 1-2mm. barely enough to even see unless your looking directly at it and paying attention. Isnt this normal though ?
Rotors dont appear to have any dammage. Pads arnt that old but I'll probably change them anyway to see if this helps unless you guys think it might be something else.

I don't understand totally what you mean by what you mentioned, but it all appears to be normal sounding to me.
Rotors arent fastened to anything if your wheels are removed. Wheels are what hold them in place. Pads can slide inward and outward freely on the PAB depending on how far the caliper pistons are sitting.
Some brake pads are noiser than others when brakes are applied.

I'm just wondering why the fronts arent doing it too because they were put on at the same time and obviously those get a lot more use.
I'm thinking it's just me and I only recently noticed it because the car is so out of tune. I used to not be able to hear the radio over the exhaust but now can hear every little rattle or sqeek due to no exhaust tone anymore.
If you haven't already, pull the caliper from its bracket. Take out the caliper sliding pins. Clean them all nice with a ton of brake cleaner. Inside the holes and everywhere. Coat the pins with some brake caliper grease.
Also replace the anti rattle clip and pad clips.
Sorry I wouldn't know exactly the cause of the problem, but I would do those since they should be routine maintenance anyway. That will at least filter out some of the possibilities. Ive heard the caliper guide pins on some cars can become seized. I also used some of the red gooey disc brake quiet stuff on the back of the pads. The pads actually sit pretty close to the rotor and that is normal.
Nice wheels by the way

Pads are suppose to drag, so you will hear it a little. The only time I think I have heard mine is when it rained and there is surface rust on the rotors. But I would not worry about the noise unless it is really bad. Like z28bryan said, clean up the guide pins. Take the pads off and use a wire brush on the pins. Then finish with the brake clean.
Oops, I didn't mean use a wire brush on the "guide pins." Those are the greased "bolts" that slide with the caliper. I ment use a wire brush on the external metal tabs that the pads slide on. Just wanted to clear that up.
