Override couplings suit the following hydraulic brake systems

Be sure to buy a brass 3/16-inch adaptor to insert into the Master Cylinder. The 3/6-inch tube will have a flared end, and this needs to be fitted into an adaptor to seal the connection properly.

The adjustment nut on the head of the coupling is a 1/2-inch BSW thread. This nut prevents the coupling from jumping on the tow ball and creates and tight fit by removing slop that can occur through wear,

How to properly adjust trailer coupling nut

  • Put pressure on the coupling head to firmly on the tow ball.
  • Loosen the nut.
  • Screw down the thread so that you can feel it touch the top of the tow ball.
  • Now tighten the locking nut being careful not to unscrew the threaded screw.

Your coupling should now be tight and ready to tow.

Note: You will also require a parking brake lever and a cable kit or perhaps master cylinders.
