Equipped with a hydraulic 3/4 master cylinder, this override coupling is suited for trailers with a GTW between 750kg and 2000kg and for trailers that use a hydraulic braking system. Featuring a sliding shaft body with a coil spring that gets compressed when the vehicle brakes, the compression of the spring activates the braking system by pumping fluid to the brakes. The quick release mechanism also allows for quick and easy connection to a 50mm towball. For extra security, there is a padlock facility to prevent detaching of the coupling. The Sunrise hydraulic override coupling is ADR Approved and Tested with CTA-061099. Advantages
