When should the trailer brake be used?

The use of trailer brakes is particularly essential under heavy braking conditions, which helps in maintaining control and stability of the towing vehicle and trailer. When the trailer is equipped with its own braking system, engaging the trailer brakes during situations where significant stopping power is required ensures that both the vehicle and the trailer decelerate in a coordinated manner. This prevents potential issues such as trailer sway or loss of control that can occur when one does not utilize the trailer brake adequately.

In regular driving, relying solely on the towing vehicle's brakes may suffice unless conditions change. Emergency situations may require immediate action, but the trailer brake should already be engaged if the driver anticipates heavy braking. While constant use of the trailer brake at all times may not be necessary and could instead lead to wear and tear or unnecessary wear on the braking system, knowing when to apply it effectively enhances safety during heavier braking scenarios.
