Disc brakes use a rotor and caliper to create friction, offering superior heat dissipation and consistent performance, especially in demanding conditions. They are commonly used on the front wheels of modern vehicles.
Drum brakes use a rotating drum and brake shoes, providing a cost-effective solution with simpler design, often found on rear wheels. Though less efficient at dissipating heat, they are reliable for lighter braking needs.
Both systems play vital roles in ensuring vehicle safety and performance.
