Go far to take you to the brake drum

The brake hub, also known as the brake drum or brake drum, is a cast iron shaped like a tambourine, which is fixed to the tire and rotates at the same speed. The brakeWhen using oil pressure to push the brake shoe to contact the inner edge of the brake drum, the friction force generated by the contact will inhibit the rotation of the tire to achieve the purpose of the brake. In layman's terms, the hub of the brake is like a metal drum or bucket over the hub, and the bottom of the bucket is rubbed against the brakeThe hub of the wheel makes the car stop.The brake drum is an important component of the drum brake system. The inner surface of the drum is where the brake device produces the brake torqueBuy. The diameter of the drum for drum brakes may be smaller than that of the disc for disc brakes with the same brake torque obtainedA lot of. Therefore, to obtain strong braking power, large vehicles with heavy loads can only apply drum brakes in the limited space of the wheel rim. drumThe type braking system is generally installed in the rear wheels of large vehicles.Maintenance method for brake drumWhen the wear of brake drum reaches the limit value (for example, the limit value of brake drum with diameter of 180mm is 180mm), the brake drum should be replaced.Carefully clean and inspect the brake drum and wheel bolts for wear, damage and dimensional tolerances, as well as whether the inner surface of the brake drum is in good conditionGood condition. If any problem is found, please replace it with a new one.After the brake drum is serviced, inject the hub with multi-purpose grease.
