Why is it important for you to replace your brake hardware when you change your brakes?

Inside each drum sits one wheel cylinder and two brake shoes, which are bolted to the backing plate. When you press the brake pedal, hydraulic pressure is transmitted from the brake master cylinder to the wheel cylinder, causing the pistons to expand, pushing the brake shoes against the inside surface of the drum.
How are brake shoes used in a drum brake system?
An emergency brake shoe system is essentially a mechanical drum brake system; the brake rotor is actually a rotor / drum combination. The brake shoes in these applications are generally the same as in a drum brake system, however a cable and lever is used instead of a wheel cylinder to push the shoes against the inside of the drum / rotor.
