I have a 2007 G35 Coupe 5AT... Lately I've noticed that when I put the car in Reverse, it makes a squealing sound as the car rolls backwards. I thought it was my brakes but it happens when no brake is applied...

Any ideas as to what it could be?

 

Your parking brake is not on, is it? Sounds dumb, but it's happened.

 

I never use my e-brake but I will double check it anyway when I hop in the car later... I wonder what it could be though

 

If your brake pads are worn considerably, the wear indicators could be permanently pressed against your rotors.

My Maxima had a similar issue, and would make a squeaking noise in reverse. I took the rear brakes apart, and found that the pads were so skinny that the squealers were mashed up against the rotors, so they'd make noise regardless of whether I had my foot on the brake or not.
