Brake rotors wear because during use, brake pads are pushed against them while the rotors are turning. It's the friction between the moving part and the staationary part that slows the vehicle down. Pads wear too, usually quicker.
Brake rotors wear due to use, they are considered a service item.

Brake rotors wear just as brake pads do and when they wear down beyond minimum specs they become unsafe. Good brakes are a # 1 priority.
Bad rotors
As long as your rotors are not warped, or you have not let the brake pads wear to the point they defaced the rotors, there is no need to change them. Just install new brake pads. Rotors can last the life of the car.
usually it will to the brake pads wear a little or it could be your rotors
To stop bicycle disc brakes from squeaking, try cleaning the rotors and brake pads with rubbing alcohol or a specific disc brake cleaner. Also, check for any contamination or wear on the brake pads and rotors, and adjust the brake calipers if needed. If the issue persists, consider replacing the brake pads or rotors.
Rotating rotors can improve a vehicle's performance by enhancing braking efficiency and reducing wear on brake pads.
Brakes shudder due to uneven wear or warping of brake rotors. This can be resolved by resurfacing or replacing the rotors, and ensuring proper installation and maintenance of the brake system.
You either have a bad brake caliper or the brake hose is bad.
No, new brake pads should not be tight against the rotors during installation. There should be a small gap between the pads and the rotors to allow for proper braking performance and to prevent excessive wear on the pads and rotors.
In general, normal wear can cause the rotors to become groved. The pads wear "into" the rotor during regular use. At some point, the rotors may need to be turned or replaced, and the pads may need to be replaced. Both the turning/replacing of the rotors and the replacment of the brake pads is done at the same time. Few if any professionals will attempt to "short cut" a brake job by just doing one thing.
Are you sure the rotors are chrome. If they are chrome plated, the plating WILL wear off. They may be made of a Chrome Moly steel.....which is typical for rotors because of it's strength.
