Which type of brake system typically provides better stopping power?

Disc brakes are known for providing better stopping power compared to drum brakes. This enhanced performance is due to several factors. First, disc brakes have a larger surface area that is exposed and more effective in dissipating heat. When brakes are applied, the friction between the brake pad and the disc creates heat; if this heat is not dissipated effectively, it can lead to brake fade, where the braking power significantly decreases.

The design of disc brakes allows for better ventilation and cooling compared to drum brakes, which can become heat-soaked more quickly. Additionally, disc brakes tend to provide a more consistent braking performance under various conditions, such as wet weather, because the open design allows water to run off more easily.

Another advantage is that the construction of disc brakes generally enables faster response times and improved modulation, making it easier for drivers to control their stopping power more precisely. Overall, these factors contribute to why disc brakes are preferred in many modern vehicles, especially those requiring higher performance and safety standards.
