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 a 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, cable kit, or master cylinders.
