Firstly, exceeding the maximum allowable diameter of a brake drum can detrimentally affect the vehicle's braking performance. When the diameter is too large, the brake shoes may not make proper contact with the drum surface. This reduced contact area limits the friction generated during braking, which can lead to increased stopping distances—an alarming safety hazard in emergency situations. Moreover, improper brake drum size can result in uneven wear of brake components, leading to further complications and costs for maintenance.

1. Specialized Tools Unlike disc brakes, drum brakes require specific tools for effective maintenance and repair. A drum brake tools kit typically includes a brake shoe tool, a spring tool, and a brake adjuster tool among others. These specially designed instruments make it easier to disassemble and reassemble the brake components without damaging them.
