Among the different braking systems, which type of brake has a greater tendency to lock the wheels when braking abruptly?

Question

DentroTest · Accepted Answer

The correct answer is drum brakes. This is due to their mechanical design, which creates a 'self-energizing' effect: when the brake shoes press against the inside of the drum, the wheel's rotation pulls the shoes tighter against the surface, making it harder to modulate the braking force. Additionally, drum brakes dissipate heat less efficiently ('fading'), which can make their behavior unpredictable. In contrast, disc brakes cool better and offer more progressive and linear braking, making it much harder to unintentionally lock the wheels.
