Brake shoe adjustments are typically made on the backing plate. The backing plate serves as a surface to which various components of the drum brake assembly are mounted, including the brake shoes. When adjustments are necessary, they are often performed through access points on the backing plate, allowing technicians to change the distance between the brake shoes and the drum.

This adjustment is crucial for maintaining the proper function of the brake system, ensuring that the shoes engage the drum at the correct distance, thus improving braking performance and extending the life of the brake parts. Making adjustments at this location is practical since it allows for easy access and minimizes the need for extensive disassembly of components.
