How can I stop the brakes coming on when I am trying to reverse my Ifor Williams trailer?

The most common remedy for this problem is to carry out the brake adjustment procedure as outlined in the IWT User's Handbook. This is something we recommend is done every 2 months/1000 miles in order to keep your trailer braking system in optimal working condition. If trying to reverse up steep inclines or very uneven ground, a manual reverse kit that overrides the trailer's auto-reverse may be available from your IWT distributor (dependant on the age of the trailer).
