When checking the trailer handbrake, what are you looking for?

When checking the trailer handbrake, the primary concern is ensuring that it engages and releases properly without sticking. A well-functioning handbrake is crucial for safety, as it needs to effectively keep the trailer secure when parked, especially on inclines or uneven surfaces. If the handbrake does not engage fully, it could lead to the trailer rolling away, posing significant hazards to both the vehicle and surrounding individuals.

Conversely, while the visibility of the handbrake paint, signs of rust, or the response time under pressure may seem relevant to overall maintenance and operation, they do not directly address the critical functionality of the handbrake system in terms of its primary purpose, which is safe engagement and release. Thus, validating that the handbrake operates smoothly without sticking is essential for ensuring the trailer's stability when it is not in motion.
