Ok I just installed rear brakes and rotors on my 07 G35 coupe.

Parts:
CZP G35 Rotors - Stock Fitment, Rear 05-07 or 06 AWD Cross-Drilled/Slotted Non-Brembo Coupe 05-07
Hawk Performance Ceramic G35 Rear 03-06 Sedan, 03-07 Coupe

Issue: When driving I can hear the pads or something rubbing

I don't hear any squeaking but I definitely hear rubbing. When I initially installed the rotors I made sure I had no rubbing or any weird noises. Installed the torque member, caliper, and pads; that's when I started hearing rubbing.
I took the brakes, caliper, and torque member off and checked for rubbing and nothing "no noise . Put them back on and the rubbing returned. I hoping that it will go away after I wear them in but....

So what am I missing?

Thanks in advance,

 

You might need to lube the sliding pins on the calipers. If they dry out they won't "float" like they should leaving the pads rubbing on the rotors and that's not a good thing. Your rotors also might be rubbing the dust shields but that's more of a grinding/screeching noise though.

 

As suggested, I would check the dust shields.

 

More then likely you are hearing the pads rubbing on the rotor. Its not uncommon when you install new pads and rotors due to the thickness of the pads. Same thing happened to me 2 weeks back. I replaced all 4 rotors, pads and both rear calipers. Form me I just drove it for a week and the rubbing subsided. When you checked for rubbing did you have everything assembled? Just take the wheel off and spin the hub with your hand. Use a flashlight and visually inspect the pad and rotor area.

Some other things to check-
Check to make sure the rotor is flush on the hub. If there is rust or corrosion on the hub the rotor wont sit flat against the hub. This would cause the rotor to stick out a slight bit making contact with the outside pad. Not common though.
Check sliding pins as others have mentioned. You should have removed them and cleaned/lubed them anyways as part of the brake service. There is one sliding pin that always has a rubber seal around it. Those are notorious for swelling and freezing inside the torque member and limiting the sliding movement.
Did you replace any of the hardware on the torque member? There are shims that come with most brake pads that you can replace. If they aren't installed correctly they can slightly protrude and rub the rotor.

 

Lion-O, it looks like the rubbing went away after about 60 miles so I should be good to go. But I'm going to go back and lube those sliding pins because I did not do that the first time.

 

I had the same problem when I installed my whole set of rotors/pads but after you break them in, you won't hear it anymore. It's just the pads rubbing a little bit

 

Yep. They're nice and quiet now and look good but now I need to do the fronts. The only reason I did the rear is b/c my left rear caliper locked up and worn the pads down. So that gave me a reason to replace and I couldn't resist the drilled/slotted rotors
