Brick may look like a sturdy wall to attach a deck to but that is not the case. Brick is only a siding and should never support much of the load if any at all. You should never attach a deck to just the brick. You should always go through the house band joist or house foundation wall and carriage bolt the deck to the home. The brick isn't attached to the home well enough to prevent a load shift and keep the deck from pulling way from the house all together. The deck may fall and take down the entire wall of bricks. When bolting on the ledger with any bolts you choose, do not tighten the bolt enough to crush the air space behind the brick wall. If the bolts are too tight, the wall can buckle, and the bricks above may fall down on top of you.  If you are attaching the deck to a brick wall, most of the load should be resting on a beam set close to the home.
