No. 12, A3, gucheng industrial park, longyao county, xingtai city, hebei province.The brake drum is also the brake drum, which is actually the drum brake on the brake disc. Brake drum is part of a drum brake system in which two pairs of half-moon shoes are pressed by a piston against the inner wall of the tympanum, causing friction to stop the wheel from spinning.
The advantages of drum brake pan
Drum brakes have a good self-braking effect, since the brake to make the disc open, the wheel rotation with the extension of the brake drum distortion an Angle (of course not so large that you can easily see) the brake to make the external tension (brake braking force) greater, the situation is more obvious.
Therefore, generally large vehicles or the use of drum brake, in addition to the lower cost, large cars and small car drum brake, the difference may only be large pneumatic auxiliary, and small car vacuum auxiliary to help the brake.
Disadvantages of drum brake pan
Because the drum brake to make the piece sealed in the brake drum, causing the brake to make the piece after the wear of the chip can not be dispersed, affecting the contact surface between the brake drum and the plate and affecting the brake performance.
Because the brake system is not sealed, so the fine debris of brake wear is constantly deposited on the brake, the centrifugal force of the disc brake can throw out all the water, dust and other pollution, in order to maintain a certain cleanliness. In addition, the disc brake is easier to service than the drum brake because of its independent parts.
