To make the rub, mix together black pepper, coriander, paprika, garlic powder, onion powder, dill weed, mustard, celery seed, and crushed red papper in a small bowl. Coat entire brisket with the rub.
Fire up smoker or grill to 225°F, adding chunks of smoking wood chunks when at temperature. When wood is ignited and producing smoke, place brisket in, fat side up, and smoke until an instant read thermometer registers 165 degrees when inserted into thickest part of the brisket, about 6 hours.
Transfer brisket to large roasting pan with V-rack. Place roasting pan over two burners on stovetop and fill with 1-inch of water. Bring water to a boil over high heat, reduce heat to medium, cover roasting pan with aluminum foil, and steam brisket until an instant read thermometer registers 180 degrees when inserted into thickest part of the meat, 1 to 2 hours, adding more hot water as needed.
Transfer brisket to cutting board and let cool slightly. Slice and serve, preferably on rye with mustard.
