They are rather large looking on the pics. If you are happy on a ladder it
can be done. But it could take you 30 mins to get the three bricks out.
You will need to lash the ladder or get some one to foot it. You will be
banging away quite hard here.

Start with a plugging chisel and cut the joint out, snap brick in half and
then remove the rest. You will be ok in patches up to 5 providing there is
no lintels etc nearby. You will also need a small bolster - electricians
chisel and a decent flat cold chisel. You could also drill all the joints
out with a hammer drill or SDS drill.

Damp down out brickwork with water and replace bricks using a stiff mortar
mix. Have some slate handy to drive into the top bedjoint - between the
top of the last new brick and bottom of old one.

although these are sold for lifting floor boards they are the same width
as a brick is high i.e. 3" 75mm . A bricklayers bolster is 100mm 4" wide
and will be no use for getting a brick out.
