Brake lock lever kit for Tektro Auriga Twin

Triobike Taxi rickshaws come with brake levers with locks for parking. If the correct technique for releasing them is not followed (squeeze and hold brake lever while flicking open the lever lock!), then they can break. 

This is the replacement item for this, there are left and right variations.
