TITLE: FMVSS INTERPRETATION

TEXT: This responds to your May 6, 1976, request for permission to remove the brake system from two trucks that were manufactured with brake systems conforming to the requirements of Standard No. 121, Air Brake Systems.

From the description of the problems you have encountered with the vehicles, I assume that you do not intend to remove the entire brake system, but only one or more antilock systems installed in satisfaction of the "no lockup" requirement of S5.3.1 of Standard No. 121. Section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. @ 1397(a)(2)(A)) prohibits, with one exception, knowing disconnection of the antilock system by a manufacturer, distributor, dealer, or repair business. Your dealer's refusal to remove the devices is probably based on this prohibition.

A person that does not fall into these categories is not prohibited from disconnection of the systems. Other State or Federal requirements, such as those of the Bureau of Motor Carrier Safety for operation in interstate commerce, may prohibit disconnection. In any case, the NHTSA urges that you not disconnect safety devices without consulting the vehicle manufacturer with regard to the safety configuration of the vehicle.

SINCERELY,

CITY OF MARION

May 6, 1976

Gordon Lindquist Regional Office National Highway Safety Administration

The City of Marion purchased two new Ford trucks in 1975 for use in the Sanitation Department, Serial No's N 80 FVW 47128 and N 80 FVW 47129. These trucks are used for garbage pickup within the city and the brake systems are presenting problems. As I understand this is the Federal Regulation SM2SF-121. I have asked the local Ford dealer, Kennedy Ford, Inc., to remove this system as we can not keep the trucks on the street due to downtime caused by this system. They, of course, refused to do so because of the regulation.

The purpose of this letter is a request for permission from you to allow the system to be removed.

These trucks have been out of service three times since the purchase and each time is for two to three weeks. I feel this brake system is a safety hazard when used for the purpose stated above.

Thank you for your consideration.
