N.Y. Vehicle & Traffic Law § 382-b: Service brake system

§ 382-b. Service brake system. Every motor vehicle of a passenger car

or station wagon type, registered in this state and manufactured or

assembled after June thirtieth, nineteen hundred sixty-seven, and

designated as a nineteen hundred sixty-eight or later model, shall be

equipped with a service brake system of such design that rupture or

failure of an actuating force component of any single brake shall not

result in complete loss of braking function. The braking function may

be obtained by hydraulic or other means through the normal service brake

mechanism.

"Actuating force component" as used in this section shall mean the

brake master cylinder, brake actuating cylinder, brake line, brake hose,

or similar components performing like functions if the brake systems are

other than hydraulic.

In the event of rupture or failure of an actuating force component,

the unaffected brakes shall be capable of applying an adequate braking

force to the vehicle.
