Hold-down springs hold the brake shoes against the backing plate when the brakes are in a released position. A hold-down pin fits through the back of the backing plate, the spring placed over the pin, and a metal cup locks onto the pins to secure the hold-down springs to the shoes. Other springs are used on the adjusting mechanism. Brake springs are high quality, capable of withstanding the high temperatures encountered inside the brake drum.
