Abstract
A supplemental brake system operates in cooperation with a motor vehicle's extant emergency brake system for selectively slowing a spinning wheel. A selector valve communicates with the vehicle's vacuum system and conduits are sized to cause a delay in the slowing of the spinning wheel. Further, the system provides for the gradual extension of the emergency brake cables which is unaffected by changes in vacuum levels in the vacuum system. The operator has full control of the vehicle during the system's operation.
