That is what happened on the 120 I got this weekend, talked to my friend that owns a shop, it does help with support, and he suggested putting that back on with silicon or chalk, I can ask if he would scrap the old stuff off and I did not think of that, but I would definitely suggest keeping the brace on. I have seen people try to remove the braces on 40b's and the glass starts to bow and next thing you know, water everywhere. This has significantly more pressure, so I would keep as much bracing on there that it came with.
