I also had great service from Mark at Brake Buddy Technical Support regarding an air leak in the pressure regulator. He correctly diagnosed a small rubber tip that worked itself loose, told me how to repair it, and helped me over the phone with some questions.
I won't use any other braking device for my toad.
