could you explain in more detail how it is not working?
Are the brands not showing up - on home page or on product page? not scrolling? not clickable?
Have you adjusted the block for the brands so that you new brands are assigned to the block for display? Just adding them to the manufacturer list, doesn't get them to the brands scrolling block.
Happy to try and assist you, but would be helpful to have more info about your issue.
