Hi there, quick question, and its probably a simple one for you guys ..... When I reverse my Eriba backwards up a slight slope the drawbar gets stuck in .... and the brakes stay on .... ???? ... I have to yank it forwards with the car to get it back out again ??? ....... do you know whats wrong with it please ?? many thanks Mike

normally the hitch moves back applies the brakes somehow the brakes then release to allow reversing, on level ground,
on a hill it may take more force for the brakes to release in reverse, if they still don't release
it could be the brakes require looking at to get them adjusted correctly, it could be they are to well adjusted, a qualified person will know.

"I'm not sure there's anything wrong with it."

perhaps not
but can only say what we experienced and how the service person mended ..

agree always move forward after ward to extend the piston thingy
