About Vehicle Brake Input

I am now developing a vehicle project using blueprint.

And now I would like to control how much my vehicle brake, when there is a different in throttle input between previous frame, and current frame.

For throttle input, we got the “Set Throttle Input” which allow an input -1.0 to 1.0 .
But for braking, I can only find “Set Handbrake Input” which only accept “true” or “false” value. Is there any method like “Set Brake Input” which accept an floating point value, should that I can control the brake of the vehicle?

I had to have something quick last time i messed with this and i think the easiest solution was to just make my own braking by reducing velocity on tick by a value i set on input.
