At its core, the integral drum parking brake system consists of a drum, shoes, and various hardware that engage to secure the vehicle in place. The drum is typically mounted on the wheel hub and rotates with the wheel while the vehicle is in motion. When the driver engages the parking brake—usually through a lever or button—the brake shoes press against the inner surface of the drum, creating friction that effectively prevents the wheel from turning. This simple yet effective mechanism ensures that the vehicle remains stationary, even on inclines.
