A method and rocker arm assembly for actuating an engine valve are disclosed. The rocker arm may include an integrated hydraulic circuit used to control a lost motion piston. A reset piston may be included in the rocker arm to selectively reset the position of the lost motion piston. A control piston may also be included in the rocker arm to selectively lock the reset piston into a reset position. The rocker arm assembly may be used to achieve compression-release or bleeder braking, main intake, main exhaust, brake gas recirculation, and/or exhaust gas recirculation valve events.
