What are signs that brake linings may be worn?

The presence of thin linings and scoring on the drum serves as clear indicators that brake linings may be worn. When brake linings are sufficiently thin, they are less effective at generating the necessary friction to halt the vehicle, which can directly compromise braking performance and increase stopping distances. Scoring on the drum itself indicates that metal-to-metal contact has likely occurred due to the brake linings wearing down too thin, causing a rough and uneven braking surface. This not only diminishes the overall efficiency of the braking system but can also lead to more significant damage and costly repairs if not addressed timely. Regularly checking for these signs during a pre-trip inspection is essential for ensuring vehicle safety and reliability.
