What secures the non-expanding end of the brake shoes to the axle?

The anchor pin plays a crucial role in the functioning of brake systems by securing the non-expanding end of the brake shoes to the axle. This is important because it provides a stable pivot point for the brake shoes as they move against the brake drum to create friction and reduce wheel speed. When the brakes are applied, the other end of the brake shoes expands outward, pressing against the drum, while the anchor pin keeps the non-expanding end in place, allowing for effective braking performance.

The anchor pin is integral to the brake assembly, ensuring that the brake shoes are properly aligned and can function as designed. Without this component, the brake shoes would not be able to pivot effectively, leading to diminished braking power and safety concerns.
