Please note:

If you wish to attach a length of timber to a brick wall, and you find that the screw stops going in any further, it's likely that you are doing something wrong -

This is to be expected if you didn't drill and plug the wall.  The screw will work it's way through the plaster, and stop when it hits the bricks.

This also, of course, means that it's not really attached to the wall, either.
