Image Number 3 for United States Patent #5638923.
A snow break system, as a supplemental break device to a regular break system in a vehicle, comprises at least a pair of brake boosters. Each of the brake boosters mounted under the vehicle has a frictional head made out of a heavy duty material. A hydraulic booster drives the frictional head downward to confront a road surface to cause a considerable frictional force. A mechanism controlled by an operator of the vehicle controls the positions of the brake system, being either in a released position or an engaged position. When the snow brake system is in the released position, the brake pedal operation actuates the regular brake system. When the snow brake system is in the engaged position, the same brake pedal operation actuates both of the snow brake system and the regular brake system.
