adjusting breaks

I called TM today to find out where they recomended putting a jack to lift the TM to adjust the breaks. The service person I talked with said on my 04 to just use the jacks to lift it off the ground and it would not bother the frame.(one side at a time) I have read other post that say not to do this. Any opinions?
When I called I asked to speak with Ed; the lady I talked with said his Father had passed away and he was at the funeral.
