The main types of brake systems include disc brakes, drum brakes, and anti-lock brake systems. Disc brakes consist of a rotor that rotates with the wheel and are clamped by brake pads when force is applied, effectively slowing down the vehicle. Drum brakes operate using a set of brake shoes that expand against the inner surface of a drum, providing braking force through friction. Both of these systems are commonly used in vehicles for their effectiveness and reliability.

Additionally, anti-lock brake systems (ABS) are not a brake type in themselves but rather a safety feature integrated into both disc and drum brake systems to prevent wheel lockup during hard braking, thus enhancing vehicle control and stability.

The other options focus on components, materials, or types of braking mechanisms not considered primary systems in themselves. For instance, while semi-metallic and organic brakes refer to the material composition of brake pads, they do not define distinct brake systems. Hydraulic and pneumatic brakes concern different operating principles but are not categorized in the same way as the primary brake types used in most vehicles. Similarly, electric and mechanical brakes represent specific actuation types but do not encompass the broader classification of brake system types.
