Did mine earlier in the year for the same reason and did help, I was advised that I could either follow the book and do it properly, or just lift the pin remove some shims and bolt back, if no movement then all is fine, and thats the easiest way and they way others have been told, so I did just that.
All you have to hope is that there are some shims in there :lol:
Be careful not to twist the brake lines.
