A McHitch mechanical Override Coupling is the ideal solution for trailers/Caravans with an ATM of up to 2000Kg. Braking systems that use an override principal meet legal requirements, as long as they provide adequate braking for the trailer and tow vehicle combination.
The principal of this type of coupling is a sliding shaft passing through the housing of the coupling. As the tow vehicle slows down the force of deceleration is passed through the coupling shaft and pushed either on a mechanical linkage (for mechanical brakes) or on a linkage connected to a hydraulic cylinder providing hydraulic pressure to a braking system (hydraulic brakes).
This type of coupling is most efficient if the ball load is not excessive and when load levelling devices are not used.
When reversing, the attached collar would be put in position to prevent inadvertent brake application. The collar should be removed from the shaft during normal towing use.
This kit comes complete with Mechanical Override Brake Plate for mechanical brakes and for hydraulic brake applications, this coupling would be fitted with the McHitch Hydraulic brake conversion kit. (Sold separately).
