Auckland, New Zealand – The following post was recently published on the RNZ (Radio New Zealand) website and concerns ongoing investigations and concerns about the parking brake operation of certain Nissan trucks sold in the country. As the article points out, the survey actually dates back to five years ago.
The Transport Department told the industry yesterday that the Sanwa Seiki parking brake control valves on various Nissan trucks must now be replaced.
The security alert came out again in 2017 and 2019, when the police were investigating a truck that was out of control.
According to industry documents, Dunedin police investigated a fatal truck crash related to this ten years ago.

On some trucks produced between 1993 and 2005, the parking brake in question was installed on the right side of the driver's seat.
If the truck is not changed in September, the truck will be banned from the road.
The previous alert has informed the owner of the brakes to be thoroughly inspected, and a qualified certificate inspector was asked to do the inspection, but no replacement was ordered.
The 2019 warning said: “Due to a potential parking brake failure, the New Zealand Police and the Work Safety Agency are investigating another truck out of control.”
"Considering to further reduce the risk, but at the same time, this alert involves maintenance of the parking brake control valve."
New alerts will be upgraded.
It said: "It has been determined that the risk of failure of the valve is partly due to the position of the control valve and partly due to the way the valve functions, which may prevent the locking of the actuator rod."
"We ask all owners of Nissan vehicles to replace the original Sanwa Seiki parking brake control valve with another graded application control valve within the range of..."
It is recommended to move the new valve to the left side of the actuator.
