rubbing from brakes or rubbing from frame
Your brakes are probably getting low and they are rubbing against the rotor.
brakes wore out maybe
Most times, the squeaking and rubbing noises are caused by brake pad wear, but you say the brakes are fine. Otherwise, if by constant rotation speed you mean the squeaking/rubbing noise is present even when the brakes are not applied, you might want to get the wheel bearing inspected
The best way to tell when you need brakes is by squeaking, when the brakes are rubbing against the metal, when your brake pedal goes all the way to the floor and when you are running out of break fluid.

You have got the breaks wet and they have rusted slightly and the growl is the surface layer rubbing off.
Worn bearings, loose rotor, warped brake rotor, sticking brakes.
