The drum brake system is specifically designed to utilize a drum and shoes as its primary components. In this system, the brake drum, which is a cylindrical component, rotates with the wheel. Inside the drum, there are brake shoes that are lined with friction material. When the driver applies the brakes, hydraulic pressure forces the shoes outward against the inner surface of the drum, creating friction that slows down the wheel.

Drum brakes are often used on the rear wheels of many vehicles due to their ability to provide effective stopping power, especially at low speeds. They are typically less expensive and lighter than disc brakes, making them a popular choice for certain applications.

Other types of brake systems, such as disc and hybrid systems, utilize different mechanisms and structures. For instance, disc brakes consist of rotors and calipers, and power brake systems may involve enhancements to standard braking systems through vacuum or hydraulic assist, but do not employ a drum and shoes for their operation. Thus, the defining characteristics of the drum brake system confirm that it is indeed the correct answer.
