advantages
1, has the good from the brake drum brake function, because the brake to make out, combined with the rotation of the wheels of the brake drum of the distortion of a perspective (of course, but not big enough to let you easily can see) brake to land tension (dynamic braking system), the greater the situation becomes more obvious, therefore, generally large vehicles or use drum brake, in addition to low cost, big cars and small cars of drum brake, the difference may only have large mining pneumatic auxiliary, and small mining vacuum auxiliary brake to help.
2, low cost: the drum brake manufacturing technology level is low, but also the first used in the brake system, so the manufacturing cost is lower than the disc brake.
3, the installation of hand brake mechanism is easy.Some rear wheel with disc brake models, will be installed in the center of the brake disc drum brake hand brake mechanism.
Specialized in castings,forgings and machinery parts.
