In my images with brick walls, I have started using iso-surfaces that use the
brick pigment-pattern to define the shape of the bricks and the mortar as
separate objects.  I apply turbulence to the brick pattern to get less perfect
brick edges, and then also apply pigment patterns to the visible face of the
brick, (for me the Z-axis), to apply a texture to them.  I then use some
techniques I found to vary the color/texture of the bricks so they vary rather
than having a uniform texture, but still preserving a single texture per brick.

I have attached an example.
