Question: 1 / 400

Which type of braking system is most commonly used in modern automobiles?

Drum brakes

Drum brakes are the most commonly used braking system in modern automobiles. Drum brakes are cost-effective, simple to design, and reliable in various driving conditions. They are especially effective for rear-wheel braking in most cars. While hydraulic brakes (option C) are also commonly used in automobiles, they are generally associated with disc brakes rather than drum brakes. Electromagnetic brakes (option B) and pneumatic brakes (option D) are not as commonly used in modern automobiles for regular braking purposes.
