Abstract
A mechanical braking system is provided for a vehicle having an electric propulsion system which is utilized for retard speed regulation. While the retard speed regulation is normally performed via electric braking, in some conditions the electric braking is not able to maintain a desired speed for the vehicle. In this condition, upon receipt of a signal from the electric propulsion system, the mechanical braking system is automatically activated so as to maintain the vehicle at the desired speed.
