2006 New York Code - 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.
