Brake shoes stop a car by exerting pressure on the:

The brake shoes stop a car by exerting pressure on the brake drum. When the driver presses the brake pedal, this action activates a hydraulic system that causes the brake shoes to move outward. As these shoes expand, they press against the inner surface of the brake drum, which is attached to the wheel. This friction between the brake shoes and the drum generates the necessary force to slow down or stop the rotation of the wheel. The design of the brake drum and shoes allows for effective braking through increased surface contact and friction, crucial for halting the vehicle's motion safely and efficiently. Understanding this mechanism is essential for grasping how traditional drum brake systems function in vehicles.
