Yep. A trick most people learned back in the days of triumph 7″ SLS front brakes.
On the Nimbus (bought from a friend as it didn’t live up to his expectations) the front brake was useless despite having brand new shoes fitted. A quick run around the block proved that he wasn’t exaggerating, it really was pitiful.
When dismantled, it became clear that one shoe hadn’t even been contacting the drum, so it was all reassembled with care and Copaslip, then the back-plate locknut tightened with the front brake squeezed hard on.
Never do stoppies, but at least it’s now safe to ride in traffic.
