Dear Mr. Cords:#This is in reply to your letter of September 19, 1972 asking whether the new hydraulic brake safety standard precludes the provision of a device using the service brake pressure to supplement normal parking brake performance.#Standard No. 105a does not prohibit the inclusion of such a device as original equipment in a motor vehicle, provided that the vehicle can meat the parking brake system requirements of the standard using the mechanical system alone.#Yours truly,Richard B. Dyson,Assistant Chief Counsel;
