When trailer brakes do not release after stopping, the correct response is to inspect the system for a malfunction and ensure that the air supply is adequate before attempting to move. This approach is crucial for safety and effective troubleshooting.

Inspecting the braking system allows you to identify any issues such as air leaks, malfunctioning valves, or electrical failures that could be causing the brakes to stick. Additionally, confirming that the air supply is adequate is important because trailer brakes operate using air pressure. If there is insufficient air pressure, the brakes may not release properly. By conducting this inspection, one ensures that the vehicle is safe to operate and prevents potential accidents or further damage.

The other options present less safe or ineffective methods. Simply driving slowly in hopes that the brakes will release does not address the underlying problem and could lead to dangerous situations on the road. Using the foot brakes to force the brakes open could exacerbate the issue, potentially damaging the braking system or causing loss of control. Finally, although calling for roadside assistance can be necessary in some situations, it does not provide an immediate solution and should be considered after ensuring the situation is evaluated and documented. Therefore, inspecting the system and ensuring air supply are foundational steps in dealing with this issue properly.
