Speed brakes are not necessarily the best solution to an overspeed for all aircraft types. At highish levels, like 410, aggresive airbrake usage will easily take an aircraft like an E190 to the other end of the speed tape and beyond, without a significant change in airspeed. But reducing thrust to idle will provide relief. Fortunately, E190s have such small engines that they very quickly spool up to cruise thrust from idle.
