What Are Drum Brakes?

A drum brake system's primary components include a wheel cylinder, brake drum, and brake shoes. Though most vehicles now feature front disc brakes, it is not uncommon for modern vehicles to still feature drum-style rear brakes. The brake shoes include a metal backing plate and friction material on their outer face and are separated by the wheel cylinder when the brake pedal is depressed. The friction material on the outside of the brake shoes presses against the inside of the brake drum, and the resulting friction helps to stop your vehicle. Over time, the friction material on your brake drums will wear down, leaving only the metal frame of the brake shoe, which makes noise and can cause damage when it contacts the brake drum. If you notice a squeaking or a scraping sound when braking, this may be caused by worn brake shoes. If your parking brake isn't holding your car in place, replacing your brake shoes may also be the solution, or you may find that your brake shoes or parking brake cable need to be adjusted. It is also important that brake drums be resurfaced or replaced when the brake shoes are being serviced to ensure a smooth contact surface and optimal braking performance. It is also recommended that your drum brake springs and hardware be inspected and replaced if needed during your drum brake service to keep the brakes working at their best and to prevent the brake shoes from sticking.
