Drum brake advantages

Drum brake advantages, self-braking effect: Drum Brake has a good self-braking effect, because the brake to make the film, the more the wheel spins with the external brake drum twisting at an angle (not so large that you can see it easily) , the more tension (braking force) is applied to the brakes, the more obvious it is, in general, large vehicles use drum brakes. In addition to the lower cost, the difference between the drum brakes of a large vehicle and a small vehicle may only be the use of large pneumatic AIDS, while the vacuum aids of a small vehicle assist in braking. Low Cost: Drum brakes are manufactured at a lower level and are the first to be used in braking systems, so they are cheaper to manufacture than disc brakes. Drum brake defect, because the drum brake to seal the disc in the brake drum, resulting in brake disc wear after the grinding can not be dispersed, affect the brake drum and the contact surface to affect the brake performance. The advantages of disc brakes, as the brake system is not sealed, so the brake wear thin cut can not be deposited in the brake, disc brake centrifugal force can all water, dust and other pollution can be thrown out to maintain a certain degree of cleanliness. In addition, disc brake parts are easier to repair than drum brakes because they are independent.
