What is the role of brake shoes in drum brakes?

To supply hydraulic pressure

To press against the inside of the drum to create friction

The role of brake shoes in drum brakes is to press against the inside of the drum to create friction. When the driver applies the brakes, hydraulic pressure is generated within the braking system, which moves the brake shoes outward against the inner surface of the rotating drum. This action generates friction, which is essential for slowing down or stopping the vehicle. The increased friction between the shoe and the drum converts kinetic energy into heat, allowing the vehicle to decelerate effectively.

The hydraulic pressure option relates more to how the braking system functions but does not describe the specific role of the brake shoes. Holding the drum in place is not a primary function of the brake shoes; instead, they must be free to move against the drum to provide the necessary braking force. Lastly, enhancing aesthetic quality is unrelated to the functional aspects of brake shoes, as their primary purpose revolves around braking efficiency and performance.
