The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.

However, like any automotive component, drum brakes have their downsides. They can be prone to overheating, especially during extensive use, and may contribute to longer stopping distances compared to disc brakes under certain conditions. Consequently, regular inspection and timely replacement of worn components are crucial. This is where drum brake kits come into play, making it easier for vehicle owners and mechanics to conduct thorough repairs.
