Sent my 2012 Scudo in for 45km service and it came back with the handbrake adjusted to six clicks and so it won't hold the van on a slope. The service guys told be all sorts of crap including that there is no adjustment and it must have come in that way. It has always been only 1 to 2 clicks.I have downloaded the workshop manual but unable to make it run. Can anyone help? Pref with diagram or instructions.
