Aircraft; Human Factors
Following an uneventful preflight and flight; while landing at Airport ZZZ we experienced a loss of brakes and thrust reversers resulting in an over run of runway X.  The plane departed the departure end of the pavement into the dirt with no known damage or injury. In hindsight I believe that I was focused on why the brakes were not actuating and continuing to attempt to deploy the thrust reversers; I failed to revert to emergency braking handle.

LR-40 flight crew reported running off the end of the runway when they experienced failure of brakes; thrust reversers; and autospoilers after touchdown.
