I would like to add one more thing to this thread addressing the bleeding process. Adjusting the shoes to almost stopping the drums is excellent advise and there is no substitute for the old fashioned two man show of a pedal pumper and a bleeder valve person. I bought the vacuum pump and canister kit since I was alone. Bled and bled and bled to no avail. Got a pedal pumper in the cab and quickly had pressure. New gadgets aren’t always the best. Was that 2 things?
