Brake drum is also a brake drum, in fact, the brake disc of the drum brake. The brake drum is part of a drum brake system in which pistons apply pressure on two semilunar shoes against the inner wall of the tympanium, creating friction to stop the wheels from spinning.

Advantages of drum brake pan

Drum brake has a good self-brake effect, because the brake to make the flak, the wheel rotation with the flak brake drum twist an Angle (of course not so big that you can easily see) brake to make the flak tension (brake brake force) greater, the more obvious the situation.

Therefore, the general use of large vehicles or drum brake, in addition to the lower cost, large car and small car drum brake, the difference may only be large pneumatic assistance, and small car vacuum assistance to help brake.

Disadvantages of drum brake pans

Due to the drum brake to seal the disc in the brake drum, resulting in the brake chip wear after the chip can not be dispersed, affecting the contact surface of the brake drum and the brake performance.

Because the brake system is not sealed, so the fine particles of brake wear are constantly deposited on the brake, and the centrifugal force of the disc brake can throw out all pollution such as water and dust to maintain a certain cleanliness. In addition, disc brakes are easier to maintain than drum brakes because the parts are independent.
