Regular maintenance of brake drums is critical to ensure optimal performance and safety. Over time, brake drums can experience wear and tear from the heat generated during braking, which can lead to warping and cracking. Fleet operators should regularly inspect brake drums for signs of damage, including scoring or excessive wear. In most cases, it is advisable to replace brake drums when they are worn beyond the manufacturer's specifications.

Animation effectively illustrates this process, showing how the rotation of the drum causes it to spin while the shoes are forced outward. This outward movement occurs due to the expansion of the brake shoes, driven by the movement of the pistons. The friction generated between the shoes and the drum produces the braking force needed to slow down or stop the vehicle.
