Brake rotor/rotors are out of round / warped. Check rotors and REPLACE as needed.
The center nut is for the hub assembly. You need to remove the screws on the rotor. The screws might be stuck to the rotor when you try to take it out. If this is the case, be careful when you use the screwdriver. You might round out the screw head. When the screw is hard to remove, I usually use a 1/4" socket wrench, 1/4" socket, and screwdriver bit. The screwdriver bit will fit inside the 1/4" socket. This gives you extra torque and won't round out the screw as a screwdriver might do. Once the screws are out, the rotor should come right off.
More than likely a front or rear brake rotor is out of round. Depending on what model and year vehicle it could be a brake drum out of round also.
Out of round or metal-metal on the pads or (possibly) bad bearing.
