Please no. If you use expanding fasteners you will crack the brick.
You have to fit this "dry" first to get the dimension right.
Get some stud/threaded rod. Drill a hole in the brick so the stud just slips in. Having got the stud the right length, i.e. into the hole and enough for the object to be secured and the nuts to attach it. Mix up a generous amount of epoxy cement and fill the hole completely. You don't need fancy equipment for this. Then before the epoxy sets screw the studs into the holes wiping away the epoxy that oozes out. If using five minute epoxy maybe mix two or more batches one batch for each hole. Leave to set , better overnight. Then mount the object to be secured onto the studs and screw some nuts onto the studs and Bingo.
