When checking the trailer's brakes, what should be avoided?

When checking the trailer's brakes, it is essential to avoid ignoring any debris that could affect the brake function. Debris can interfere with the performance of the braking system, potentially causing the brakes to malfunction or become less effective. Ensuring that the area around the brakes is clean and free of any foreign objects is critical to maintaining safe operation.

Effectively, all components of the braking system should be operable, and any obstruction can compromise safety by preventing the brakes from responding properly. Therefore, during a pre-trip inspection, being vigilant about removing debris is crucial to ensuring that the braking system operates as intended under various conditions.
