Jack one of the tires up and pull your breakaway pin and then try to rotate the tire by hand. When the brakes are correctly adjusted the brakes will grab and stop the wheel from turning within less than one inch of wheel turn. Once brakes have engaged, there is almost no movement either direction until you put the switch pin back in.
I always test my breakaway system each time I hitch, just makes good sense to know your system is working before moving. If not working, then it is time to troubleshoot and repair before moving trailer.
I do the same at the start of each season to make sure each individual brake is working. And my wheels barely turn before locking up.
Measuring current does not prove the brake is actually engaging.
