The invention provides an equine infectious anemia vaccine that provides immunity to mammals, especially equines, from infection with equine infectious anemia virus and which allows differentiation between vaccinated and non-vaccinated, but exposed, mammals or equines. For this purpose, a pedal opposing force can be set by a characteristic curve as a function of a pedal position which is predefined by the driver, and can give the driver a pedal sensation even if there is no reaction of, for example, a conventional brake system. The multiple zone testing system facilitates testing each zone singularly and performing commingled tests without pulling out of the well.
