The ´full information´ part is not very natural. ´More information´, ´all the information´ or ´further infortmation´ would go better here. Overall, this phrase is possible but is very formal, so it will probably only be appropriate in specific situations. Hope this helps!

You can say: "I'll save my judgement until I get further information" "I'll hold off on my judgement until I get more information" Hope that helps!
