An inspection of a vehicle's brake drums and rotors includes checking for what?

  1. Only cracked brake drums

  2. Only broken rotors

  3. Both cracked or broken brake drums and rotors

  4. Neither cracked nor broken drums and rotors

The correct answer is: Both cracked or broken brake drums and rotors

When inspecting a vehicle's brake drums and rotors, it is important to check for both cracked or broken brake drums and rotors. A cracked brake drum or rotor can lead to brake failure and put drivers and passengers in danger. A broken rotor also affects the braking system and can cause the vehicle to pull to one side when braking. Simply checking for only one type of damage (like A or B) would not provide a comprehensive inspection of the brakes. Additionally, option D is incorrect because it suggests that neither cracked nor broken drums and rotors need to be checked, which is not true. All components of the braking system should be inspected for safe operation.
