I'm talking about the rod that goes down from the actual lever and keeps the button pressed in on the brake light switch. Did it come installed on your levers? I don't remember installing a separate part onto the levers before installation. Maybe it was left over and I threw it away without realizing what it was. Could it have fallen off? Maybe I can buy just that part from zeta? I could probably fabricate something but it wouldn't look as good. I don't want to think about how long I've been riding around not having a working brake light. Without the button at the front brake pressed in the brake light is constantly on.
