Word: Brake Drum
Definition: A brake drum is a hollow, round piece made of cast iron that is attached to the wheel of a vehicle. It works as part of the braking system to help slow down or stop the vehicle when the driver presses the brake pedal.
While "brake drum" specifically refers to a part of a vehicle's braking system, "brake" on its own can refer to the act of slowing down or stopping something.
Understanding "brake drum" is important for anyone learning about vehicle mechanics or safety.
