Park brake control valve maintenance and operational requirements for Nissan CK330, CW330, CW380, CW400, CM180, CW400 and CG400 vehicles manufactured between 1993 and 2005.

Further to the safety alert of May 2017, the NZ Transport Agency is telling CoF inspectors and operators of these Nissan trucks to urgently and carefully check the park brake. This is necessary because once wear occurs, the lock pin is able to hold the park brake on but it may not be fully engaged. Consequently, the park brake can be unintentionally released by a knock or vibration.

It‘s important to check if the park brake lever can sit with the locking pawl only partially engaged. If so, the vehicle must not be operated until the hand control has been serviced or replaced. It should also be failed for any CoF.
