New Sound Jake Brake v1.0

It is the first engine brake I think for Peterbilt and Kenworth, it is made for the interior and exterior.

Installation: open “My Documents” / open folder “American Truck Simulator” / Open Folder “mod” / paste the mod there.

After starting the game and go to edit profile in the top left says a small “management we” icon to click and activate the mod and apply changes and go!
