Thanks for the input all.
I didn't get a chance to check for air leaks today. Yes I am very gentle on the brakes, mostly using the engine brake then light pedal pressure till stopped. My wife was a CDL examiner, and sometimes it's like being tested. LOL. I think I will also check the slack adjusters as maybe I AM too light on the pedal and they aren't adjusting themselves.
I am not against having the brakes looked at, but I would like to exhaust some things I can do before spending the $$$.
