If a vehicle inspector doubts the condition of a park brake assembly, they can request that the 4085D form be presented to provide proof of inspection/servicing in the last two years (once the vehicle exceeds two years from date of first registration in New Zealand, or every CoF from date of first registration if entry certified as a used vehicle).
