Retrieve handbrake at 6J

Hello in the round, I had the handbrake reset today at my 6J after my Ibiza rolled downhill the day before yesterday despite the handbrake attracted. At my 6L the TÜV had also noted too much “game” at the handbrake. After the workshop visit today the handbrake is at least as tight as it should be. Even after three grids one notices a corresponding train. According to the workshop the handbrake would automatically adjust, so that a rearrangement in the who I did not find anything in the manual that the hand brake would be adjusted. Is there a trick for this? Thank you very much and thank you very much! Lois13051
