E-brake mapped to wheel button, holds e-brake too long when I press it.

I have a moza wheel i use for fh6. I mapped the e-brake to a button, but when I press the button, it holds the e brake for longer than how long I hold the button, so I always spin out if I use it. If I touch the button for .1 seconds, the game holds the e brake for 2 seconds. I use this button in EA WRC and it works fine, not a sticky button, its either a setting im missing or its something else. Does anyone have a solution or is anyone else experiencing this? Thanks.
