Try the wrench on something else that isn't going to break & get a feel for it.

This is a good possibility. Some wrenches operate by a brief change in resistance to turning and not an audible click. It can be easy to miss. That said, it could be a bad wrench too. I have a $20 5 to 100 ftlbs wrench from Harbor Freight that more often than not fails to indicate at anything over 40 ftlbs. Fortunately, I've tightened enough bolts over the years that my spidey sense was tingling the first time I tried it on a 50 ftlbs bolt. It felt like I was giving it more than was needed, so I tried another wrench that I have, and it indicated at 60 ftlbs. So I was already 10lbs over.
