If Brakes hold 125% leave them alone. Micros should be low movement on brakes to prevent faults. Supposed to be certified by KONE to do any brake work. The 214 relay is the Dynamic Braking Relay. It is used to keep the machine from taking off like a bullet if the brakes do not hold. It shorts all the fields together so you have a big huge magnet and the car can only move about 9fpm instead of running away. The 214 is an add on relay on older units and may not have been added, in which case you pick brake care will take off like a rocket. If brakes fail without a 214 relay anyone would be cut in half that got in the way of movement. If KONE failed to add the 214 relay, it is a safety hazard and should be added by them or get a lawyer to go after them. Maybe even an Inspector.
