Like other vehicle systems, brakes need to be inspected and undergo routine maintenance. Brake service inspection isn't a big job for the experienced professional, you may not have realized this, but your brakes get a quick inspection when your car is in the shop for any other reason, such as tire rotation or alignment service. Generally speaking, a brake inspection is simply checking the fluid level, making sure it isn't contaminated, and visually checking the amount of wear on the brake pads and rotors.
As brake pads wear down over time, the brake fluid fills the gap to hold them open at the proper distance from the rotor, which makes the brake fluid appear lower in the reservoir. When it reaches a certain point it needs to be topped off. In order to top it off, it can't be a closed system. As an open system, road debris, grit, or grime can get in or condensation can form in the brake lines. Such a concept causes the need to flush the system and refill it with new clean brake fluid. Alternately, the fluid can get burnt or start breaking down on a molecular level. In such a case, the fluid has to be exchanged, and it indicates a deeper problem a certified technician needs to diagnose and repair.
Modern cars have a computer which lights a warning signal on your dashboard when the brake pads need replacement. There's also a thin wire embedded inside the brake pad which causes a horrible squealing noise when brake pressure is applied once they are worn down to nearly the end of their useful life.
Theoretically, steel rotors are designed to withstand the pressure of the brake pads. In the real world, everything wears down over time. Some make and models of cars have rotors that can be resurfaced, others have rotors that are too thin and just have to be replaced. In practical application, this is an aspect of the car which violates the general rule about repair being cheaper than replacement. For the expense, it's better to replace the rotor and know you have a functioning new one than worry about whether the resurfacing was adequate.
