Which component helps to locate shoes on the backing plate?

The anchor pin is a crucial component in drum brake systems, as it serves to secure the brake shoes in place against the backing plate. By anchoring one end of the shoes, the anchor pin allows the other end to pivot when the brakes are applied. This pivotal motion is essential for the shoes to expand outward against the drum, creating the necessary friction to slow down or stop the vehicle.

In contrast, other components like the adjusting screw are responsible for maintaining the proper distance between the brake shoes and the drum to compensate for wear. The connecting spring plays a role in returning the shoes to their resting position after braking, but it does not serve to locate them on the backing plate. The brake pedal is a control mechanism operated by the driver and is not directly part of the brake assembly. Therefore, the anchor pin is the component specifically responsible for providing stable positioning of the brake shoes relative to the backing plate.
