Hi, I was at the Dekra for HU today. Failed since refueling brake without function. The examiner sat down to test in the car, briefly hit – max 5kmh, full braking, no function. Drawbar completely pushed into each other. I called home, WW dealer. He already moaning and said “They never get this, because of the return automatic the brake only works from about 10kmh. Tell that to the examiner!” I into the car. 20kmh, full braking, caravan brake, tire squeak. A Iso back to the Dekra, the examiner tells everything. Then he went in to the phone and came out after several phone calls with badge. He then said something about “You also have a Winterhoff 3000 Antishlinger clutch and the WW weighs now empty about 1200kg, can also because the brake does not immediately address. ” Now I am of course unsure. Should I have the brake set? Or is that so correct that the brake does not pack in the low range?
