ABSTRACT:
An educational vehicle is provided in which the driver-student is provided with a conventional braking pedal and the passenger-teacher is provided with a braking pedal to override the driver-student braking pedal in order to effect a braking operation. Furthermore, there is provided a counter braking pedal which is employed to override the operation of the brake by the driver-student. The counter braking arrangement may involve a mechanical system provided with a mechanical advantage so constructed and arranged that the operation of the counter braking device is capable of preventing or reversing the operation of the brake by the driver-student.
The counter braking operation can also be effected through an electrical or hydraulic apparatus or the like.
