If this does not work (as it happened in my case), it is possible because <br> generated by some scripts after the JS .remove() code is executed.
To check if I was right, I set a rather long timeout and all my unwanted ones disappeared after that time. So in the end I just decided to put plain CSS
#grape1 br, #grape12 br { display: none; }
and eveybody happy =)
