2016 305RE my second brake job

Thats right my second!. In 2018 I scheduled a bearing repack and brakes were destroyed. Spent $1300 for the brake job. While on a trip had a brake locking up, had a trailer sales shop back it off and still that same brake locking up. The tire was shot.
Last week had the brakes looked at and they had to cut off spring hold downs off to remove the drum. Had three drums turned one replaced.
I’m a retired truck driver, I use my brakes sparingly. Have engine brake and don’t follow closely. Have brake gauge set at 5.
Looking for answers why this is happening.
