Had a customer bring his truck to us for MOT. He stated that it is slow building the air up and the park brake doesn't want to release or is slow releasing. We have come across this problem a few times and it is very common on a DAF Truck. The air drier is at fault with the multi point protection valve playing up. New parts fitted and the truck is back how it should be working. Another happy customer:) A service and a bit of maintenance goes a long way. I don't think this filter has been changed for a while!
