Which of the following statements is true regarding brake maintenance?

The statement that brake components should be replaced as they become worn is true and reflects a critical aspect of brake maintenance. Over time, brake components such as pads, rotors, and shoes are subjected to wear due to friction and heat generated during braking. If these components are not replaced in a timely manner, it can lead to reduced braking effectiveness, increased stopping distances, and potentially unsafe driving conditions. Regularly monitoring the condition of brake components and replacing them when they reach their wear limits ensures that the braking system functions properly, enhancing vehicle safety and performance.

In contrast, maintenance strategies that disregard regular inspection, claim that brake fluid can last indefinitely, or suggest that disc brakes require no maintenance are misleading and can lead to severe safety issues. Regular upkeep and awareness of wear limits are vital to maintaining a reliable brake system.
