SIMPLE: How to make vehicle go in reverse

I am using the advanced vehicle that Unreal provides. I need to us the “BrakeInput” Node. However, from my knowledge, in order to use this I must uncheck the vehicle movement property “Use Reverse as Brake”. When I uncheck this box my car cannot drive in reverse. (While checked it can). Key bindings are not the issue. If I set a dummy variable with the throttle input, it actually shows -1 and 1 when going in reverse and forward respectively. However, even when the throttle shows -1 the vehicle moves forward. Any ideas?
