Final answer:
When you apply the brakes, the brake shoes/linings press against the brake drum.
Step-by-step explanation:
When you apply the brakes, the brake shoes/linings repress against the brake drum. The brake drum is the rotating part of the brake system that is connected to the wheel. When the brakes are applied, the pressure from the brake fluid causes the brake shoes to press against the drum, creating friction and slowing down the wheel.
For example, in a hydraulic brake system, when the driver pushes the brake pedal, a force is exerted on the pedal cylinder. This force is then transmitted through a lever and hydraulic system to the wheel cylinders. The pressure created in the wheel cylinders causes the brake shoes to press against the brake drum, resulting in the braking action.
