Flashing tape is only any good on smooth brickwork and even then not
that good. You should use a grinder to cut a channel in the mortar
betweek brick layers and let some decent flashing into said gap (you
can get an L-shaped profile PVC panel that's good for fixing split
flashings). It's then supposed to be pointed up with fresh mortar but I
think bitumen sealant does a better job.

Thank-you for your post. You've answered several questions that have
been running around my brain for a while.
