The present invention is directed to a locking assembly for use in a rocker arm assembly for an engine brake assembly. The rocker arm assembly includes a rocker arm pivotally mounted on a shaft. The rocker arm has a first end and a second end, wherein the first end includes a cam follower and the second end includes an actuator assembly for operating at least one valve during a braking operation. The improved rocker arm includes a locking assembly for releasably securing the rocker arm to the shaft to prevent pivoting of the rocker arm during a positive power operation. The locking assembly includes a releasable latching assembly located on one of the rocker arm and the shaft. The locking assembly also includes a latch receiving recess located on another of the rocker arm and the shaft. The releasable latching assembly engages the latch receiving recess during a positive power operation. The releasable latching assembly disengaging the latch receiving recess during an engine braking operation such that the rocker arm can pivot about the shaft.
