A compression release brake valve is then opened at least in part by fluidly connecting a brake actuator to a source of high pressure actuation fluid. Next, a valve closing timing that results a valve seating velocity that is less than a pre-determined velocity is determined. The compression release brake valve is then closed at the valve closing timing at least in part by fluidly connecting the brake actuator to a low pressure actuation fluid reservoir.",
