When should you check brake adjustments?

Only before long trips.
Regularly during pre-trip inspections.
Never, if the brakes feel normal.
Only during adverse weather conditions.

The correct answer is: Regularly during pre-trip inspections.

Checking brake adjustments regularly during pre-trip inspections is critical for ensuring the safety and functionality of the air brake system. This involves verifying that the brakes are properly adjusted before operating the vehicle, as misadjusted brakes can compromise stopping power and increase the risk of accidents. Consistent checks help identify any issues early on, allowing for timely maintenance. While checking brakes only before long trips may seem reasonable, it neglects the fact that brakes can wear differently based on daily driving conditions and usage. Additionally, relying on the feeling of "normal" brakes can lead to dangerous oversights, as some brake issues may not be perceptible to the driver until they become severe. Checking only during adverse weather conditions misses the opportunity to ensure optimal brake function in all circumstances, not just when conditions are challenging. Therefore, making brake adjustment checks a regular part of pre-trip inspections is essential for maintaining safety standards and operational reliability.
