You never said the issue, you said you were trying to eliminate lockup on command, which is not a problem you are trying to solve nor anything there is any real reason to do. But if you're shorting the brake switch and its still locking up, you are creating a situation that could become unsafe yes.
And yes removing swaybars is pretty unsafe too. There was a time when I thought that might be acceptable but not anymore.
Either way you've decided that you want to do this and don't want to say why (where we might help you with the actual problem) so go ahead and do it, but don't sit here and tell us we're attacking you.
