On the new brick execute:
setfattr -n trusted.glusterfs.volume-id -v
0x8786357b9d114c01a34baee949c116e9 <new-brick-path>

Before bringing glusterd, new brick up, do the following:
 From the mount point execute 'mkdir <non-existent-dir-name>; rmdir
<same-dir-you-created-before>; setfattr -n trusted.abc -v def
<gluster-mount-path>; setfattr -x trusted.abc
<gluster-mount-path>'

Could you please post the output at this point of all the bricks? i.e.
both the healthy bricks and old bricks? I would like to check that there
are no mistakes in the operations you performed above.

Once I confirm things are fine, do:
start glusterd on the machine with new brick and self-heal should
automatically start.

These steps are from latest document: http://review.gluster.com/8503
Let me know if you have any doubts.

I will try to get this in as soon as possible.
