Systems and methods for providing partial bleeder braking engine valve actuation are disclosed. In an embodiment of the present invention, a cam may be provided with a main exhaust lobe, a partial bleeder lobe and an inner base circle portion between the two lobes. A rocker arm including an internal rocker passage may be operatively connected to the cam. The rocker arm may contact a valve bridge at a central portion. The valve bridge may be operatively connected to first and second engine valves at its first and second ends, respectively. A slave piston incorporated into the first end of the valve bridge and a master piston may be incorporated into the central portion of the valve bridge. A hydraulic circuit may be provided between the master and slave pistons. A bleed hole may be provided above the slave piston. The master and slave pistons may be selectively actuated and the bleed hole may be selectively blocked and unblocked to provide partial bleeder braking as a result of the valve actuation motion imparted from the cam to the valve bridge through the rocker arm.
