Ok, so I will buy some wood blocks
thanks for the info, I already emailed them a few weeks ago and didn´t get a responce, so I think I really have to call them. Problem is that the dutch and the german regulations on trailer brakes are totally different, although we are both in the european union and everything should be easier now
To all the european forum members who read this threat:
Do you still have the electric brakes or did you change them to surge brakes. If you changed them - why?
Thank you folks!!
