Cypher. I did the same brake in wrong way around thing - like Duh - once you know right? But it was good then started locking up and then soon could do skids in the driveway at about 10kmh.. Got them in the right way and all cool since, but I was worried about the drums being close to the minimum 230mm as per BIG letters on the drum itself. They were right on 230 so I bought new ones ... They are like 2mm smaller .. It's not a big difference! Maybe check yours if they have run right out of wear.. I have a set of 230mm if you want them..
