Six men killed in incidents involving faulty parking brakes

Alan Nichol, Brian Edwards, Mark Lee, Phillip Loving, Graeme Rabbits and Allan Ranapia. These six men have died in incidents involving cardan shaft parking brakes since 2010. A coroner investigating Graeme Rabbits' death has declared the brakes inherently unsafe. It's an assessment the N-Z Transport Agency doesn't agree with. But key transport industry figures are backing the coroner, and Graeme Rabbits' father Selwyn is campaigning for change so no one else is killed. Checkpoint's Louisa Cleave and Jimmy Ellingham report.
