What do you need to check for when inspecting the trailer's brakes?

When inspecting the trailer's brakes, it is crucial to ensure they function properly and are free of debris. This is essential for safe operation because the brakes are a vital safety feature that allows the vehicle to stop effectively. Proper brake function involves examining components like the brake pads, drums, and air lines (in the case of air brakes) to confirm they are in working order and not worn or damaged. Additionally, ensuring that they are free of debris is important, as any obstruction can hinder their performance or lead to potential failure during driving.

Other considerations, such as noise, can be indicators of issues, but simply checking for noise does not encompass the comprehensive inspection needed for brake safety. Similarly, while the appearance of the brakes and related components is important, being "painted correctly" does not impact their functionality. Focusing solely on the brake lights disregards the mechanical aspects of braking performance, which are crucial for safe driving.
