Been having a problem when I couple up ,when the hitch head comes down on the tow ball I have tp give it a tap for the handle to go down, I had a good look under the hitch head this morning and the moving parts behind the rear brake pad looked very dry I gave them a very slight taste of graphite grease which solved the problem , dropped the hitch head on to the tow ball a couple of times and the handle moved smoothly down,
