Ok, my van was in for a service. The service centre contacted the dealer service centre. According to the dealer service centre it is a well known problem/issue with the Isuzus in South Africa. They were not willing to divulge the solution for this. <img src="/forums/images/graemlins/angry.gif" alt="" />

In the meantime I'll try and find the balance between the rear drum brakes and the hand brake to see if it will solve the problem.
