What is a key sign of trailer brake wear?

A key sign of trailer brake wear is demonstrated by uneven braking or the occurrence of squeaking sounds when braking. This indicates that the brake components may be worn unevenly, which can affect the overall effectiveness and safety of the braking system. Uneven braking typically occurs when one side of the trailer's braking system is functioning differently than the other, suggesting that some parts may need maintenance or replacement. Squeaking noises can be a warning that the brake pads are worn down and are starting to make metal-to-metal contact, which could lead to more significant damage if not addressed promptly.

In contrast, constant speed during driving, increased fuel consumption, and better handling on turns do not specifically relate to the condition of the trailer brakes. While fuel consumption may increase due to a range of factors, it is not a direct indicator of brake wear. Constant speed or improved handling on turns can depend on various aspects of vehicle dynamics and load distribution rather than solely the condition of the brakes. Therefore, observing uneven braking or hearing squeaking sounds serves as a clear and specific sign that intervention may be needed to ensure safe trailer operation.
